Web2 5-(20 points) The growth rates of liquid cultures of E. coli BL21(DE3)pLysS-pET23d(+)-scFv13R4, induced or non-induced with IPTG, were determined by reading OD 600 with a spectrophotometer. WebInoculate starter culture at a 1:100 dilution into expression media containing antibiotic. Incubate at 37°C with shaking until OD 600 reaches 0.4–0.8. For most vector systems, …

WebTo reduce the cost of production of rhCIFN in E. coli , induction was accomplished by using lactose instead of IPTG. Lactose induction (14 g/L) in shake flask experiment resulted in higher yield as compared with 1 mM IPTG. Finally, with single‐step purification on DEAE sepharose, 150 mg/L of >98% pure rhCIFN was achieved. Webthis point, an IPTG solution was added at the described con-centrations (0.01, 0.1, 0.5 and 1.0 mM) and incubated for 3hat378C or overnight at 208C to induce the production of Sc_ASNaseII using the conditions, vectors and gene combi-nations described in Supporting Information Table A.2. At the end of this procedure, the cells were pelleted, the ... preety formater json
