Fig. 3From: An alternative for proteinase K-heat-sensitive protease from fungus Onygena corvina for biotechnology: cloning, engineering, expression, characterization and special application for protein sequencingPurified NHSSP variants and SDS effect. a Purified del-NHSSP expressed by pPink-HC-del-NHSSP clone. Lane M, Amersham™ LMW Calibration Kit For SDS Electrophoresis; lane 1, NHSSP sample denatured by heating in Leammli electrophoresis loading buffer (with SDS); lane 2, NHSSP sample denatured by heating in Leammli electrophoresis loading buffer (with SDS) in the presence of 5 mM PMSF. b Very long electrophoresis run of purified NHSSP and del-NHSSP.
