SIGNATOPE offers next generation quantitative assays for your protein biomarker of interest!

SIGNATOPE (SIGNAture epiTOPE) immunoassays are capable of detecting and quantifying protein biomarkers in humans and all pharmacologically relevant model species. Antibodies comprising epitopes of 4 amino acids are the key reagents of SIGNATOPE´s immunoassays. The short epitope allows us to establish quantitative assays for the same protein in different species and for isoforms of protein families. Even immunoassays for notoriously difficult proteins like drug transporters can be established while providing the speed and the sensitivity of an antibody-based method.
