SARS-CoV-2 Spike RBD Titer Assay Kit

It's been reported that coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

This kit is developed for detecting SARS-CoV-2 Spike RBD in vaccine samples, which can meet the needs of vaccine developers to establish antigen quantification methods for preclinical evaluation, vaccine production and quality control, and realize accurate quantification of vaccine antigen contents for COVID-19 vaccines of all technological platforms, multivalent vaccines, and VOC-specific boosters.

1. Unopened kit should be stored at 2°C-8°C upon receiving. 2. Find the expiration date on the outside packaging and do not use reagents past their expiration date. 3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

This assay kit employs a standard sandwich-ELISA format, providing a rapid detection of SARS-CoV-2 Spike RBD. The kit consists of microplate pre-coated with Anti-SARS-CoV-2 Spike RBD Antibody, an SARS-CoV-2 Spike RBD as Control, an biotin-Anti-SARS-CoV-2 Spike RBD Antibody, HRP-Streptavidin and buffers.
