Fig.2. Expression and purification of the SADS-CoV S-Fc protein.
(A) The expressions of recombinant S-Fc fusion protein were detected by Western Blot using anti-SADS-CoV Ab positive serum, negative serum and anti-Human Fc PcAb as control. (B) SDS-PAGE analysis of the purified S-Fc fusion protein. M represents standard protein markers. The band of purified S-Fc fusion protein was indicated by arrow.
