From

Recombinant Antibody

Isotype

Engineer antibody

Application

ELISA, IF

Species Reactivity

SARS-CoV, SARS-CoV2

Basic Information

Specificity

This antibody binds the amino acid residues   between 11-19 of the N protein of the SARS CoV as well as SARS-CoV-2   (COVID-19) nucleocapsid protein.

Alternative Name

NP; NC; Protein N; Nucleocapsid protein; SARS-CoV Protein N; SARS-CoV Nucleocapsid protein; SARS Coronavirus; SARS-CoV-2; SARS CoV 2; 2019-nCoV

UniProt

P0DTC9, P59595

Immunogen

The original antibody was generated by cloning the variable regions of the scFvs selected from phage display libraries into separate vectors for IgG1 heavy-chain and light-chain expression. The harvested supernatents were then purified on protein A columns. The original immunogen was the whole irradiated virion.

Application Notes

This antibody is recommended for detection   of SARS CoV2 protein N (nucleoprotein). This antibody binds both the   nucleocapsid protein of the SARS-CoV and SARS CoV-2 (2019-nCoV). Initial   characterization of the antibody for binding to 2019-nCoV was done using   ELISA. This antibody shows potential to be used for development of diagnostic   assays. Various isotype versions of the antibody namely human IgG1, IgG3,   IgM, IgA and the less common IgG2 and IgG4 are available for the investigation of their role in response to SARS CoV2. Competitive ELISA of   this antibody with CR3009 suggests that both these antibodies bind different epitopes of the N protein of SARS CoV. Thus, a combination of these two  antibodies is suggested for virus capture assays. Immunofluorescence staining   was used to demonstrate binding of CR3018 to SARS-CoV infected Vero cells.   (PMID:15650189)
