Precision proteomics for biomarker discovery

Biomarker studies which were previously limited by poor assay sensitivity, low throughput systems and insufficient sample amount are now feasible in a simple and efficient way.

For the first time it is possible to do high capacity quantification of 92 protein biomarkers in 96 samples. Conventional immunoassays have been unable to scale due to increasing antibody cross-reactivity but TATAA Biocenter offers a solution using the Multiplex platform from Olink Proteomics. It generates high quality data even in highly multiplexed formats and the opportunities are enormous for powerful analysis of multivariate biomarker patterns.

Figure 1. BioMark™ 96×96 chip generates
9,216 data points in a single run

The quantification is performed using the Fluidigm BioMark™ HD Real-time PCR Platform and generates 9,216 data points in a single run (Figure 1.).

  • Discover novel expression patterns of 92 protein biomarkers in precious biological materials.
  • High-multiplex analysis with no compromise on data quality.

TATAA uses a fast and sensitive method based on the Proximity Extension Assay (PEA®) technology. The method allows for rapid and easy testing of potential biomarkers and each assay in the 92 biomarker panel has been accurately validated for sensitivity, recovery, dynamic range, specificity and precision.

Unravel low-abundant proteins not detected before

The sensitivity of qPCR allows extremely low sample consumption. TATAA can generate more information from less sample volume which enables you to make the most out of your precious biobanked samples.

  • Down to sub pg/ml sensitivity in only 1 µl samples
