Figure 4. Purification of ScRev7 and ScRev7-C1 proteins.
(A) SDS–PAGE analysis of protein samples from different stages of ScRev7 purification. Lane 1, standard protein markers; lane 2, uninduced cell lysate (10 μg); lane 3, induced cell lysate (10 μg); lane 4, Ni2+-NTA column eluate (3 μg); lane 5, Superdex S75 column eluate (1 μg); lane 6, eluate from heparin column (0.8 μg). (B) SDS–PAGE analysis of purified truncated ScRev7-C1 variant. Lane 1: standard protein markers. Lanes 2 and 3, purified full-length ScRev7 and ScRev7-C1 variant.
