Fig. 3From: Effective production of human growth factors in Escherichia coli by fusing with small protein 6HFh8Analysis of the feasibility of original target protein liberation by TEV protease treatment. a The fusion proteins were purified by HisTrap chromatography and treated with TEV protease and the reaction mixtures resolved by SDS-PAGE. The images are representative of two independent experiments. C: after cleavage; F: fusion protein before cleavageBack to article page
