Antibody Class: IgG1
Human monoclonal antibody CR3022 was prepared via an immune phage display library, constructed from lymphocytes of a convalescent severe acute respiratory syndrome coronavirus (SARS-CoV) patient. CR3022 is a neutralizing antibody that targets the receptor binding domain (RBD) of the spike (S) glycoprotein of SARS-CoV. NR-53876 was produced in Nicotiana benthamiana tobacco plants using a transient plant expression system and purified from the total plant homogenate using protein A chromatography. This antibody preparation differs from BEI Resources NR-52392 only in the method used to extract the recombinant product from the expression host plants prior to affinity purification; NR-52392 was purified from an extracellular fraction and NR-53876 was extracted from total plant homogenate. Plant made antibody CR3022 features complementarity-determining region (CDR) sequences introduced into a human IgG1 molecule. The epitope of CR3022 does not overlap with the ACE2-binding site within the S glycoprotein RBD from severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2). CR3022 targets a highly conserved epitope that enables cross-reactive binding between SARS-CoV-2 and SARS-CoV.

NR-53876 is specific to the S glycoprotein and has been shown to neutralize SARS-CoV. CR3022 recognizes the full-length SARS-CoV-2 S1 protein fused to a human IgG1 Fc domain (S1-Fc) under reducing and non-reducing conditions, as well as a hexa-histidine-tagged S glycoprotein RBD alone, in Western blot analysis; however, CR3022 did not neutralize SARS-CoV-2 in a recent in vitro assay. CR3022 binds potently to SARS-CoV-2 RBD as determined by ELISA and biolayer interferometry (BLI) binding assays.
Applications include western blot analysis, immunofluorescence, ELISA and neutralization.
Each vial of NR-53876 contains approximately 100 ?L of purified monoclonal antibody in PBS.
