Sandwich ELISA detection of recombinant full-length SARS-CoV-2 spike (trimer) protein using BSV-COV-AB-02 as capture antibody at concentration of 5 μg/mL and a detection antibody at concentration of 1 μg/mL. Rabbit IgG antibody (HRP) was diluted at 1:10000 and used to detect the primary antibody.
Dilution started at: 1:10000
Immunofluorescent analysis. SARS-CoV / SARS-CoV-2 (COVID-19) spike antibody [1A9] detects SARS-CoV-2 (COVID-19) spike protein by immunofluorescent analysis.
Sample: BHK-21 cells transfected with full-length SARS-CoV-2 spike were fixed in 4% paraformaldehyde at RT for 30 min.
Green: SARS-CoV-2 (COVID-19) spike stained by SARS-CoV / SARS-CoV-2 (COVID-19) spike antibody [1A9] diluted at 1:2000.
Dilution started at: 1:2000
Western Blot. Non-infected (–) and infected (+, 48h pl MOI 0.01) Caco-2 whole cell extracts were separated by SDS-PAGE, and the membrane was blotted with SARS-CoV / SARS-CoV-2 (COVID-19) spike antibody [1A9] diluted at 1:1000.
Dilution started at: 1:1000
