Figure 2From: High yield expression in a recombinant E. coli of a codon optimized chicken anemia virus capsid protein VP1 useful for vaccine developmentVP1 protein expression in E. coli using various expression vectors. The VP1 protein expression in E. coli BL21(DE3) using the expression vectors, pET28a (A) and pGEX-4T-1 (B) was analyzed by SDS-PAGE and Western-blotting. Anti-His tag and anti-GST tag monoclonal antibody were respectively used for the recognition of differently tagged VP1 proteins expressed by the different expression vectors used. Lane M, pre-stained protein marker; lane 1 and lane 3, before IPTG induction; lane 2 and 4, after IPTG induction for 4 h cultivation. The solid triangle pinpoints the expressed VP1 protein.Back to article page
