HyTest specialists have been involved in cardiac troponin I (cTnI) studies for more than 15 years. Currently many well characterised antibodies directed to different regions of the cTnI molecule are available. Many of these antibodies are used in commercial assays. The company has determined antibody pairs and combinations useful for the development of high sensitivity cTnI assays, and also validated pairs suitable for lateral flow assays. A new generation of cTnI antibodies is currently under development.
Work with brain natriuretic peptides is ongoing, and BNP, proBNP and NT-proBNP antibodies and antigens are available. In addition a new type of BNP/proBNP immunoassay, the "single epitope" sandwich assay, has been developed, which differs from the conventional format of sandwich immunoassays. In the single epitope sandwich assay, the capture antibody recognises the antigen (BNP or proBNP), whereas the detection antibody is specific to the complex of capture antibody and antigen. The single epitope sandwich approach has great advantages compared with conventional assays, especially in the case of unstable antigen detection.
