Anti-SARS-CoV-2 Spike RBD Antibody, Mouse IgG1 (AS110) (Delta Specific) (MALS verified)

抗体来源(Source)

The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with Spike RBD F(ab')2. The antibody is specific against the Delta (B.1.617.2/AY.4) variant of SARS-CoV-2, and has no binding with the spike RBD of the wild type virus and the Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), Omicron (B.1.1.529/BA.1) variant.

Protocol

 

背景(Background)

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.
