Profiles of SDS-PAGE of Bt S2160-1 (Zhang et al., 2012)

Bt S2160-1 and Bti were cultured in G-Tris medium, The samples for SDS-PAGE analysis taken before and after sporation respectively and crystal proteins digested with 1uM trypsin were analyzed together. PM1: protein molecular weight marker, land 1, 4: strain proteins before sporation from Bti and Bt S2160-1 respectively; lane 2, 5: crystal proteins after sporation from Bti and Bt S2160-1 respectively; lane 3, 6: crystal proteins from Bti and Bt S2160-1 were treated with 1ug/ml trypsin.
