Protagen AG, a leading provider of products, services and software solutions for protein research based in Dortmund, Germany, relies on two Tecan HS 4800™ Pro Hybridization Stations for automated processing of its UNIchip® protein arrays for antibody characterization, and for discovery of biomarkers relevant to diseases such as multiple sclerosis, rheumatoid arthritis and cancer indications.

“After we have found a set of putative biomarkers, the crucial step forward is to test them in quantitative terms in larger patient cohorts, and this requires a highly reproducible chip processing procedure,” explained Dr Jens Beator, Director of the Protein Biochips business unit at Protagen. “Each chip usually includes a few hundred biomarkers that need to be quantified in a single assay. Careful standardization is extremely important for reproducible analysis so we always process all of our chips under identical conditions using the HS 4800 Pro Hybridization Stations.”

“It was relatively straightforward to optimize the assay for automation and to develop standard operating procedures, we also had good support from Tecan,” Jens continued. “In the past we had to perform the assays manually, which required many man hours from our technicians but now those staff are free to do other work.”

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Lab-on-a-ChipLab-on-a-chip (LOC) technology uses microfluidic chips, such as microarrays, to perform biochemical assays on a small scale. Benefits of lab-on-a-chip include the small volume of sample required as well as the speed of analysis. In selecting lab-on-a-chip devices consider the assay, cost, reliability, sensitivity and signal to noise ratio.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Microarray AnalysisMicroarrays, also known as biochips, are used for the detection and analysis of multiple genes, proteins, antibodies, or biomarkers on a single microchip. This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests. Discover a range of microarray scanners and prefabricated antibody, protein, RNA and DNA microarrays for your analysis or consider creating your own custom microarrays with a microarray printer. Find the best microarray products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Compound AnalysisCompound analysis is used to discover specific compounds that could be promising candidates for pharmaceutical use. This potential is identified when compounds have the desired effect, such as interaction with a target protein, during high throughput screening.
