White Paper: Autoantibody Biomarker Panels for Improved Disease Diagnosis
Feb 1, 2012

Oxford Gene Technology (OGT)

A new report from OGT explores the need for biomarkers as indicators of disease, and discusses the vast potential of autoantibodies as markers of early disease development. Autoantibodies are produced by the host immune system and as such are often detectable during the early stages of disease onset. In addition, they are stable, abundant, highly specific and easily purified from serum, making them ideal candidates for use in disease detection. The issues surrounding the use of autoantibodies as biomarkers are discussed in detail in the whitepaper, including their relative advantages, selection of the most appropriate discovery technology and choosing between strategies for in-house or outsourced discovery.

White Paper: How Instrument Design Affects CHN Micro-Analytical Performance
Feb 1, 2012

Exeter Analytical

A new report discusses how CHN elemental analyzer design affects operational accuracy and precision, ease of use and handling of demanding sample types.  The report examines the consequences of different commercial CHN elemental analyzer designs when the systems are run in real lab environments.
 
Data shows the impact of horizontal versus vertical combustion systems. In a horizontal furnace arrangement the sample is introduced into the combustion tube on a quartz ladle, which critically enables the removal of all sample residues after combustion.  In a vertical furnace arrangement the samples are combusted on top of previously combusted samples.  This difference is a major factor contributing to the advantages of a static system with a horizontal furnace over both the dynamic and hybrid designs.  The build-up of sample residue in the combustion zone of vertical furnace systems is shown to considerably increase the potential for poor analytical data.

According to Exeter, the most important criteria for CHN analysis in the majority of analytical laboratories is for optimal accuracy and precision across a wide range of sample types. With constant pressure to increase laboratory productivity users do not want to set up analyzers with different operational parameters for every different sample type they come across.  Test data from an independent multi-laboratory study is included in the white paper demonstrating not only the accuracy and precision routinely achievable, but also how the inherently longer term stability with a horizontal furnace design markedly decreases time lost due to the need for recalibrations and sample re-runs.

Considerable variance in instrument performance can also be seen with more demanding samples.  The advantages of a horizontal furnace design CHN elemental analyzer is illustrated with applications including time-dependent combustible samples and volatile liquids.

Technical Article: Impact of Product Resistance on Primary Freeze Drying
Nov 4, 2011

SP Scientific

Authored by Dr. Margit Gieseler of GILYOS and Dr. Henning Gieseler of the Freeze Drying Focus Group at the University of Erlangen, this new technical article discusses how product resistance (Rp) has been recently suggested as a critical product parameter (CPtP) in freeze drying because it instantaneously draws a picture of the (already dried) inner cake morphology at the point of measurement. According to SP Scientific, from a physical point of view, Rp of the dried product layer impacts the resistance to water vapor flow and thus indirectly determines the maximally allowable shelf temperature and primary drying time. In addition to providing an introduction to product resistance behavior, the article summarizes the results of trials investigating the product resistance of sucrose based on different experimental conditions and using the Auto-MTM feature of the SP Scientific SMART Freeze Dryer software. The authors conclude resistance of the product to vapor flow during primary drying is a critical product parameter that impacts several process parameters. Lack of information about product performance during primary drying can lead to sub-optimal product quality and/or problems during scale-up. The use of MTM allows an assessment of product resistance data.

Application Note: The Use of Acumen eX3 for the Identification of the Roles of Protein Kinase C (PKC) α & δ Isoforms in PMA-Induced Ectodomain Shedding
Sep 28, 2011

TTP LabTech

A new application note from TTP LabTech illustrates how the company's Acumen eX3 laser scanning imaging cytometer can be used to elucidate novel cellular pathways involved in the shedding of the epidermal growth factor receptor (EGFR). The note describes how the high-throughput imaging technology of the Acumen eX3 quantifies and monitors protein expression levels.

According to TTP LabTech, online image capture and analysis, as well as multiplexing capabilities, allows the Acumen eX3 platform to provide consistent and accurate data from complex biological systems. The shedding of HB-EGF is classically controlled by a disintegrin and metalloproteinase, ADAM17. The imaging technology of Acumen eX3 is used to determine the contributions of additional enzymatic pathways in this process. HT1080 cells, transfected with a modified, alkaline phosphatase linked, heparin binding EGFR (AP-HB-EGF) are examined by both the traditional enzymatic assay and immunofluorescence for receptor shedding in the presence and absence of inhibitors of ADAM17 and PKC isoforms. Experimental data suggest that important contributions are made by the PKC isoforms α & δ. Disruption of EGFR homeostasis is associated with a number of important cancer targets.

Report: BladeCell Disposable Cuvette for Improved DLS Productivity
Sep 28, 2011

Avid Nano

A new report from Avid Nano demonstrates how its BladeCell disposable cuvette improves dynamic light scattering (DLS) sample preparation time by a factor of 8 compared to using traditional quartz cuvettes. The 5µl BladeCell cuvette is precision molded in black polycarbonate and requires no sample preparation beyond centrifuging to reduce the possibility of dust contamination that can affect DLS measurements.  To fill, 5µl of sample is simply pipetted against the walls of the BladeCell liquid trap where it is retained by surface tension. The prepared cuvette is placed into the temperature controlled sample holder of the Avid Nano W130i, where it can be analyzed by DLS in seconds.  After analysis the sample is recovered by dipping a pipette tip into the liquid trap and removing the contents.  Disposal of the BladeCell eliminates the cleaning steps required with quartz cuvettes.

Technical Report: Precise and Accurate Measurement of Target Copy Number
Jul 29, 2011

Fluidigm Europe

This new technical note describes experimentation on a normal human genomic DNA sample using a prototype 200k Digital Array Chip on a modified BioMark System.

Fluidigm's Digital Array chips provide a platform to perform digital PCR and have been used in sample quantitation, rare mutation detection, haplotyping, and copy number variation studies. The new 200k chip prototype is more powerful and enables an even more precise and accurate measurement of target copy number.  Two forms of commercial Digital Array chips are currently available, which have configurations known as 12.765 and 48.770 (with 9,180 and 36,960 reaction chambers each).

This report shows a prototype 200,000 chamber version of the Fluidigm Digital Array chip and demonstrates that the experimental process is further simplified and the copy numbers of two single copy genes (RnaseP and RPP30) can be measured at a much greater accuracy.  The BioMark system used for the 200k chip experiments was modified by the addition of a higher resolution CCD camera.

Application Note: Automation of a Magnetic Bead Workflow for Protein Biomarker Quantification
Jul 29, 2011

Agilent Automation Solutions

This new note demonstrates how the Bravo liquid handling system provides an efficient platform for automation of a SISCAPA Magnetic Bead Workflow for protein biomarker quantification by mass spectrometry (MS).

The authors describe an automated protocol implementing SISCAPA immunoaffinity enrichment of biomarker peptides prior to quantification by MS. In the described protocol, magnetic beads coated with anti-peptide antibodies are used to bind specific target peptides from tryptic digests of plasma and serum samples, after which the beads are washed to remove unbound peptides, and the bound, purified peptides are eluted in small volumes for injection and analysis in an LC/MS/MS system.  Stable isotope labeled versions of the same peptides are used as internal standards to enable accurate quantification.  The Agilent Bravo automated protocol for this application enabled SISCAPA processing of 96 samples in less than 30 minutes, less than half the time required by traditional manual methods.

Identifying microRNAs that Can Serve as Biomarkers for Prostate Cancer
May 25, 2011

Fluidigm

Using Fluidigm Corporation's BioMark System and Digital Array integrated fluidic circuits (IFCs), researchers from the University of California San Francisco (UCSF) have identified serum microRNAs that can serve as biomarkers for prostate cancer.  The UCSF research group designed their own microRNA preAMP and PCR primers specifically to be used on the BioMark platform and then were able to identify mRNA signatures that correlate with prognosis.

To identify serum miRNAs that diagnose and correlate with prognosis of prostate cancer, the researchers at UCSF developed a multiplex quantitative reverse transcription PCR (qRT-PCR) method involving purification of multiplex PCR products followed by uniplex analysis on a Fluidigm microfluidics chip to evaluate 384 human miRNAs. Using Dgcr8 and Dicer knockout (small RNA - deficient) mouse ES cells (mESC) as the benchmark, the researchers confirmed the validity of their technique, while uncovering a significant lack of accuracy in previously published methods. Profiling 48 sera from healthy men and untreated prostate cancer patients with differing CAPRA (Cancer of the Prostate Risk Assessment) scores, UCSF researchers identified miRNA signatures that allowed them to diagnose cancer patients and correlate with prognosis. These serum signatures included oncogenic and tumor suppressive miRNAs suggesting functional roles in prostate cancer progression.

White Paper: An Introduction to High-Throughput Microchromatography
May 25, 2011

Agilent Automation Solutions

The new white paper describes how the Agilent Bravo for Protein Purification Liquid Handling Platform together with AssayMAP high throughput microchromatography system was designed specifically to meet all of the technical requirements for quantitative sample preparation for protein analysis. The AssayMAP system is comprised of a microchromatography cartridge, special associated labware, and a liquid handling device designed to interface with the cartridge and provide precise flow control in a 96-channel microplate format.

The authors describe how applications of high-throughput microchromatography for protein analysis are designed to purify, quantitate and react. In purification, the goal is to separate the target protein from all or most of the impurities present in the sample, isolating the target for further operations. In quantitation, the goal is to measure the amount of the target protein present in the sample. In reaction, the goal is to modify the target protein chemically by either enzymes or other reactants. Sample preparation protocols may involve any or all of these types of steps.

A new comparative study demonstrates that the Mirroball antibody discovery system offers equivalent data to the discontinued ABI 8200 FMAT instrument, with minimal changes to assay protocols.  The study uses the FMAT assay to look at bead-based quantitation of a soluble protein (rabbit IgG) and antibody binding to EGF receptors expressed in A459 cells. The Mirrorball system scanned the entire well, and FMAT reported data from only a 1 mm2 area in each well. Beads were identified by laser scatter on Mirrorball and fluorescence on FMAT. The Mirrorball system could enumerate beads in all wells, in contrast to FMAT, which could not detect all beads below 1 ng/mL rabbit IgG.

A new technical note from Agilent Automation Solutions describes a BioCel System that offers the flexibility to accommodate different high-throughput screening (HTS) assays as well as new protocols and hardware.  The system includes a selection of liquid handlers and readers, and an active environmental control for the entire system. A multimode reader, bulk reagent dispensers, plate washer and the Agilent Vertical Pipetting Station allow assays to be run in 96-, 384- or 1536-format.  The active environmental control used by the Agilent BioCel System allows assays to be run at constant temperature (ambient up to 37°C), avoiding edge effects often caused by transport into and out of incubators. The high precision, low volume pipettor and the large plate storage capacity allow the compound plate bank to be run alongside the assay, adding the compounds on-the-fly. No prior assay plate generation is necessary and due to the low volume capacity of the Vertical Pipetting Station (200 nL), DMSO concentrations in the assay are kept low.
