Objective To construct the prokaryotic expression vector of human HDAC4 protein and glutathione-S-transferase(GST) for protein expression and purification.Methods pcDNA3.1-HDAC4 was digested by EcoRⅠ,the hHDAC4 coding sequence was obtained and cloned into prokaryotic expression vector pGEX-5X-1 to generate novel vector GST-HDAC4.After identification of GST-HDAC4,Escherichia coli BL21 was transformed and induced by isopropyl-β-D-thiogalactoside(IPTG),and target protein was obtained after purification.The exp...
