12% (w/v) SDS-PAGE analysis of recombinant Ldc1E.
Lane 1, molecular mass standards. Lane 2, total protein of E. coli BL21 (DE3) pLysS harboring empty pET30a(+) (control). Lane 3, total protein of E. coli BL21 (DE3) pLysS harboring the recombinant ldc1E in pET30a(+). and Lane 4, protein was purified using the Ni-NTA column method. The black arrow indicates the recombinant Ldc1E.
