Fina Biosolutions_Specialty Immunoreagents

Fina Biosolutions’ Specialty Immunoreagents are a collection of reagents mainly of interest to immunologists. These reagents arose out of both our own research and requests from other scientists. Please let us know if there is a reagent you would like us to make.


TNP-Dextran and TNP-Ficoll are classic T-cell independent model antigens. Due to the wide availability of TNP immunoreagents, they serve as useful models of natural T-cell independent antigens like polysaccharides. TNP-OVA and TNP-BSA serve as T-cell dependent model antigens with the trinitrophenyl epitope. The set of TNP reagents also allows for the selection of a suitable ELISA antigen.
