SDS-PAGE results for the purification of MBP-LBT-LR11TM-His6. Lanes: 1, protein marker; 2, elute of MBP-LBT-LR11TM-His6 from a Ni-NTA column; 3, thrombin cleavage of the protein sample in lane 2; 4 to 7, elutes of LBT-LR11TM-His6 from Ni-NTA columns with an elution buffer containing 0.2% DPC, 0.3% LDAO, 0.2% LMPG, and 0.2% DDM, respectively.
