Fig. 5From: Breakdown of albumin and haemalbumin by the cysteine protease interpain A, an albuminase of Prevotella intermedia SDS-PAGE showing the stability of albumin and haemalbumin under reducing conditions at different pH. Albumin and haemalbumin (16 μM) were reduced with 3 mM DTT and incubated at 37 °C. SDS-PAGE conditions were the same as those in Fig. 3. The gels were stained with CBBBack to article page
