NSE , IRMA
The DiaSource NSE-IRMA is an immunoradiometric assay based on coated-tube separation.
Mab1, the capture antibody, is attached to the lower and inner surface affinity for Mab1. Addition of Mab2, the signal antibody labelled with 125I, will complete the system and trigger the immunological reaction.
After washing, the remaining radioactivity bound to the tube reflects the antigen concentration.
