(Synonyms: ZRC3308-A7)

Masavibart (ZRC3308-A7) is an anti-SARS-CoV-2 monoclonal antibody (IgG1 type). Masavibart shows good binding affinity to a non-competing epitope on the RBD of the SARS-CoV-2 spike protein. Masavibart can be used in combination with ZRC3308-B10 (HY-145643) at a ratio of 1:1, which is effective for the prevention of COVID-19 and the early stage of COVID-19 before the development of severe disease.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
