Antibodies binding to relevant proteins from the lysates of SARS-CoV infected Vero E6 cell. (A) anti-S1 antibody; (B) anti-S2 antibody; (C) anti-N antibody. The E.coli expressed S or N protein and the lysates were subjected to SDS-PAGE and transferred to Nitrocellulose Transfer Membrane. The blots were probed with the antisera (1:10000) and detected with HRP-conjugated goat anti-rabbits IgG.
