Figure 5From: Identification and characterization of alkaline serine protease from goat skin surface metagenome SDS-PAGE and zymogram analysis of the purified AS-protease. Lane M, molecular weight marker proteins (14.4 to 116 kDa); Solublised pellet fraction of E. coli BL21 (pET30b) (lane 1) and E. coli BL21 (pETP1) (lane 2); purified AS-protease (lane 3); zymogram of purified protease (lane 4). An arrow indicates the purified AS- protease.Back to article page
