Chloramphenicol → Kanamycin

Participants

Reaction Steps

Competent cells of MG1655/pSTV28-Ptac-Ttrp, MG1655/pSTV28-Ptac-IspSK, MG1655/pSTV28-Ptac-IspSM, or further MG1655/pSTV28-Ptac-IspSP strain were prepared, and pMW219-dxs was introduced therein by an electroporation method. The cells were evenly applied onto the LB medium containing 60 mg/L of chloramphenicol and 50 mg/L of kanamycin hydrochloride, and the cells were cultured at 37° C. for 18 hours. Transformants that were resistant to chloramphenicol and kanamycin were obtained from the resulting LB plates. Strains in which pMW219-dxs had been introduced into MG1655/pSTV28-Ptac-Ttrp, MG1655/pSTV28-Ptac-IspSK, MG1655/pSTV28-Ptac-IspSM, or further MG1655/pSTV28-Ptac-IspSP strain were designated as MG1655/pSTV28-Ptac-Ttrp/pMW219-dxs, MG1655/pSTV28-Ptac-IspSK/pMW219-dxs, MG1655/pSTV28-Ptac-IspSM/pMW219-dxs, or further MG1655/pSTV28-Ptac-IspSP/pMW219-dxs strain, respectively.
