	Overview ProteoTope Chemical proteomics Bioinformatics Cell biology Mass spectrometry		ProteoTope™ ProteoTope™ is the proprietary and unique platform of ProteoSys. This technology provides unmatched accuracy and dynamic range of protein quantification. It is based on dual radio-isotopic labelling and allows access to low abundance proteins down to amounts of 10-4 ng. ProteoTope™ is a differential technology, resulting in a quantitative display only of differential proteins in two samples. Protein biomarkers can thus be identified even from very complex biological material by applying controlled pooling schemes. Mass spectrometry-based identification of proteins is validated by independent methods (antibodies) and integration with functional cellular parameters using ProteoSys’ unique databases.[find_out_more]
