Comparison of relative expression of RBD and its mutants.A, SDS-PAGE showing relative amounts of expressed RBD and its mutants. M represents molecular weight markers (from top to bottom: 180, 130, 100, 70, 55, 35, and 25 kDa). B, relative expression of mutants quantified from the band intensities in SDS-PAGE in panel A. RBD, receptor-binding domain.
