Revvity HTRF SARS-Cov2 Spike S1 protein detection kit, 500 Assay Points

The SARS-CoV-2 Spike S1 protein is one of two part of the virus Spike protein (S). The S1 subunit is responsible for the the virus interaction with host cells transmembrane Angiotensin-converting enzyme 2 receptors (ACE2), while the S2 subunit is capable of conformational changes that allow the fusion of the viral particle envelope and host cell membrane upon S1/ACE2 binding. As such, the S1 protein is closely investigated for its role in viral infection and is reliable marker of infection as well as a potential vaccine immunogen target.
