Fig. 1From: A mechanistic approach to prove the efficacy of combination therapy against New Delhi metallo-β-lactamases producing bacterial strain: a molecular and biochemical approachSDS polyacrylamide gel of soluble NDM-1 protein fraction isolated from E. coli BL21 cells having the NDM-1 marker. The cells were induced with 0.5 mM IPTG for 3 h at 37 °C. Lane P is the NDM-1 protein of 28.5 kDa in size and lane M is the prestained protein ladderBack to article page
