Faster immunodetection has always been a target among life science researchers. Nowadays lateral flow test is the most popular format of Point of Care Test (POCT) which typically takes 15 minutes to complete and qualitatively detects a soluble antigen. In this webinar, we introduce a new immunodetection technology, direct immunohistochemistry (IHC) which also takes 10-15 minutes to complete but qualitatively detects solid phase antigens in tissue or cells. Direct IHC opens multiple new applications in pathology diagnostics and pharmaceutical companion diagnostics. Meanwhile we would like to introduce a novel inhibition lateral flow test detecting SARS-CoV-2 neutralizing antibody.
