This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment. Antibody Class: IgG Clone: 001 NR-53795 is a recombinant rabbit monoclonal antibody prepared against the fusion protein containing severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) spike (S) glycoprotein receptor binding domain (RBD) (R319 to F541) and mouse IgG Fc (mFc) domain (Sino Biological 40592-V05H) that was expressed in HEK293 cells and purified. NR-53795 is specific to the SARS-CoV-2 spike RBD as shown in ELISA, with cross reactivity to the SARS-CoV-2 spike S1 protein (Sino Biological 40591-V08B1). No cross reactivity was observed in ELISA with S1 glycoproteins from SARS-CoV, MERS-CoV, HCoV-HKU1 (isolates N1 and N5), HCoV-NL63, HCoV-229E or HCoV-OC43. The biological activity of NR-53795 was measured by its binding ability using biosensor analysis, in which biotinylated recombinant SARS-CoV-2 S RBD recombinant protein (His tag) (Sino Biological 40592-V08B-B) can bind NR-53795; the affinity constant is 0.006 nM. SARS-CoV-2 Inhibitor Screening ELISA Kit (Sino Biological KIT001) detected serial dilutions of NR-53795; the IC₅₀ is 0.59 nM. NR-53795 is functional in microneutralization in vitro using 293T-ACE2 cells infected with SARS-CoV-2 spike pseudovirus with an IC₅₀ of 0.11 ?g per mL. Each vial of NR-53795 contains approximately 50 ?g of purified monoclonal antibody in buffer. For more information please visit the Sino Biological website.
