【Abstract】 The results of the study on the cultural conditions of high expression of hbFGF by recombinant Escherichia coli hbFGF/BL21(DE3)pLysS show that with inoculum quantity as 5% of the cultural medium, adding 0.5 mmol/L IPTG as revulsant to the leavening when its OD 600 reaches 0.8, higher expre_ ssion of hbFGF can be gained. 30% dissolved oxygen and lower concentration of acetate acid are conductive to hbFGF expression.更多还原
