Fig. 2From: Codon optimization of a gene encoding DNA polymerase from Pyrococcus furiosus and its expression in Escherichia coliExpression of recombinant protein of Pfu pol in E. coli BL21 transformants with IPTG induction. The triangle symbol indicates the targeted protein band. Lane M: protein marker; lanes 1, 4, and 7: total fraction; lanes 2, 5, and 8: soluble fraction; lanes 3, 6, and 9: insoluble fraction; lanes 1, 2, and 3: transformant colony number 01 (TC-01); lanes 4, 5, and 6: transformant colony number 02 (TC-02); and lanes 7, 8, and 9: transformant colony number 03 (TC-03)Back to article page
