Purification and cleavage of Trx-Y87G2A.14 fusion protein. Samples were analysed by SDS-PAGE (15% polyacrylamide) and stained with Coomassie Brilliant blue R 250. Lane 1, 2 μg protein standards: bovine serum albumin (66 kDa), ovalbumin (45 kDa), glyceraldehyde 3-phosphate dehydrogenase (36 kDa), carbonic anhydrase (29 kDa), trypsinogen (24 kDa), soybean trypsin inhibitor (20 kDa) and α-lactalbumin (14.2 kDa); lane 2, soluble cell extract of BL21 (DE3) cells transformed with recombinant plasmid pETY87G2A.14 and induced with 1 mM IPTG for 8 hours at 25°C before applying to a column of NiCAM™-HC resin ; lane 3, 3 μg purified Trx-Y87G2A.14 fusion protein; lane 4, 3 μg purified Trx-Y87G2A.14 fusion protein after cleavage with thrombin.
