Critical Raw Materials

INFYNITY BIOMARKERS specializes in the design of recombinant proteins and antibodies. We particularly excel at identifying specific antibody binding sites to support the discovery and development of relevant biomarkers. Using epitope mapping prediction algorithms, our researchers analyze target protein sequences and try to identify the serological hotspots i.e. regions of high immunogenicity allowing them to identify the most promising B-cell epitopes and proprietary sequences. 

Optimized Antigen Mixes

Our mixes are composed of carefully selected recombinant proteins and synthetic peptides, designed to enhance detection performance compared with individual antigens.
