SARS-CoV-2 (COVID-19) Spike (S1) Polyclonal Antibody

Purified rabbit polyclonal antibody (IgG) recognising a region within the N-terminal of the Spike Protein (S1) of SARS-CoV-2 (COVID-19).

Concentration: 0.2 mg/ml

Clonality: Polyclonal

Specificity:This antibody detects SARS-CoV-2 spike protein (S1 subunit), but does not cross-react with SARS-CoV or MERS-CoV spike proteins based on our internal testing.
Form in stock: Liquid – 0.2 mg/mL.
Host: Rabbit
Immunogen: Recombinant protein encompassing a sequence within the N-terminus region of SARS-CoV-2 (COVID-19) spike (S1). The exact sequence is proprietary.

Indirect ELISA analysis. Performed by coating plate with 50μl of Recombinant Full-length SARS-CoV-2 Spike Protein at concentrations ranging from 0.625μg/ml to 4μg/ml. The coated protein is detected with SARS-CoV-2 (COVID-19) spike antibody (BSV-COV-AB-05) at 1μg/ml.
Indirect ELISA analysis was performed by coating plate with 50 μL of recombinant SARS-CoV-2 (COVID-19) spike S1 subunit protein at concentrations ranging from 0.0625 μg/mL to 4 μg/mL. The coated protein is detected with SARS-CoV-2 (COVID-19) spike antibody (BSV-COV-AB-05) at 1 μg/mL. Rabbit IgG antibody (HRP) was diluted and used to detect the primary antibody.
Dilution started at: 1:10000
Western BlotNon-transfected (–) and transfected (+) 293T whole cell extracts (30 μg) were separated by 5% SDS-PAGE, and the membrane was blotted with SARS-CoV-2 (COVID-19) spike antibody (BSV-COV-AB-05) diluted.An HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.
Dilution started at: 1:5000
Immunohistochemical analysis. SARS-CoV-2 (COVID-19) spike antibody detects SARS-CoV-2 (COVID-19) spike protein by immunohistochemical analysis.
Sample: Paraffin-embedded SARS-CoV-2 (COVID-19) Spike FFPE Cell Pellet Block.
Green: SARS-CoV-2 (COVID-19) spike stained by SARS-CoV-2 (COVID-19) spike antibody (BSV-COV-AB-05) diluted at 1:1000.
