SARS-CoV nsp3 Antibody Summary

This SARS-CoV nsp3 Antibody was produced by repeated immunizations with 3 E.coli derived proteins representing different parts of the SARS-CoV Nsp3 protein: aa 834-943 of polyprotein 1a (ADRP domain), aa 1208-1557 of polyprotein 1a (SARS-Unique Domain) and aa 1558-2040 of polyprotein 1a (Papain-like proteinase domain).
This antibody is directed against SARS-Coronavirus nsp3 protein. Cross reactivity with homologues from other sources has not been determined.

  • Western Blot 1:1000
  • Immunocytochemistry/Immunofluorescence 1:1000
  • Immunoprecipitation 1:60
Application Notes
Western Blot: Expect a band of approximately 211 kDa in size corresponding to SARS-CoV nsp3 by western blotting in the appropriate cell lysate or extract.

ICC/IF: Vero-E6 cells, grown on glass slides, were infected with SARS-CoV-Fr1 strain for 1 h at 37C. Infection occurred in PBS/DEAE/2%FCS followed by exchange to EMEM/25mMHEPES/2%FCS. Cells were fixed with PBS/3%PFA. After washing fixed cells, antibody incubation was performed in PBS/5%FCS for 30 min.

Reactivity Notes

Cross reactivity with homologues from other sources has not been determined.

Alternate Names for SARS-CoV nsp3 Antibody

  • orf1ab polyprotein (pp1ab)


The nonstructural protein 3 (nsp3) is one of the SARS-Coronavirus replicase cleaving products, encoded by ORF1a. Nsp3 is thought to be part of the viral replication complex, which is associated with intracellular membranes. Nsp3 contains a papain-like cysteine proteinase and ADP-ribose-1'-monophosphatase activities.
