Western blot analysis of EM1902-21 with N-terminal His tag-tagged SARS-CoV-2 Nucleocapsid protein (1) and Inactivated SARS-CoV-2 lysate (2) at 20ng.<br /> Proteins were transferred to a PVDF membrane and blocked with 5% BSA in PBS for 1 hour at room temperature. The primary antibody (EM1902-21, 1/500) was used in 5% BSA at room temperature for 2 hours. Goat Anti-Mouse IgG - HRP Secondary Antibody (HA1006) at 1:20,000 dilution was used for 1 hour at room temperature.
