SARS-CoV-2 IgG Detection Kit (Colorimetric Trimer Anti-Spike IgG detection)
79975 96 rxns.
EUR 765
Description: The SARS-CoV-2 IgG detection kit is designed for qualitative detection of human IgG antibodies in serum collected from individuals suspected of prior infection with the virus that causes COVID-19. This fast and simple ELISA uses the trimeric form of the SARS-CoV-2 Spike protein (BPS Bioscience #100728) to identify IgG antibodies that indicate a previous infection with SARS-CoV-2. The Spike protein is expressed on the viral membrane as a trimer, which means this kit measures IgG antibodies in a more physiologically relevant context than many other commercially available ELISA kits.

Spike Trimer (S1+S2) (B.1.351 Variant) (SARS-CoV-2): ACE2 Inhibitor Screening Colorimetric Assay Kit
78174 96 rxns.
EUR 995
Description: The SARS-CoV-2 Spike Trimer (S1+S2) (B.1.351 Variant):ACE2 Inhibitor Screening Colorimetric Assay Kit is designed for screening and profiling inhibitors or neutralizing antibodies of this interaction. The key to this kit is that the SARS-CoV-2 Spike Trimer (S1+S2) (B.1.351 Variant) protein provides a more biologically relevant model than monomeric Spike RBD protein for the investigation of SARS-CoV-2/host cell interaction. Only a few simple steps on a microtiter plate are required for the assay. First, SARS-CoV-2 Spike Trimer (S1+S2) (B.1.351 Variant) is coated on a 96-well plate overnight. Next, the proteins are blocked and pre-incubated with the inhibitor or neutralizing antibody. Upon subsequent incubation with Biotin-ACE2, the plate is treated with Streptavidin-HRP followed by addition of a colorimetric HRP substrate to produce color, which then can be quenched and measured using a UV/Vis microplate reader.
