Fig. 4From: Effective production of human growth factors in Escherichia coli by fusing with small protein 6HFh8Protein expression in 5-l fermentation. Expression profiles of 6HFh8-aFGF (a) and 6HFh8-VEGF165 (b) are shown. SDS-PAGE images in the insets indicate the expression levels of fusion proteins at the indicated time after induction. Black arrows indicate the induction time. Values are averages from two independent experiments; errors are standard deviationBack to article page
