SARS-CoV-2 Neutralizing Antibody

Product Description

Rabbit monoclonal anti-SARS-CoV-2 spike RBD neutralizing antibody

This rabbit monoclonal antibody was raised against the RBD domain of the SARS-CoV-2 S1 protein (Arg319 to Phe541, sequence below). The antibody was validated through binding assays (ELISA) and neutralization assays for its ability to neutralize SARS-CoV-2 pseudoviruses such as Ha-CoV-2 and Ha-CoV-2 variants (e.g. delta and omicron). The antibody was expressed in mammalian cells and purified as a recombinant protein. Antibody 27VBI has an extremely high affinity to RBD, and is be able to detect as low as 0.5 pg/ml RBD protein in human serum. For more information, please contact us by email: info@virongy.com
