Application

Mitomycin C is produced by a strain of actinomyces, Streptomyces caespitosus. It contains three anticancer moieties, quinine, urethane, ａnd aziridine groups. It is used to generate mitotically inactive feeder cells in cell culture systems, such as the mitotically inactive fibroblasts used in embryonic stem cell systems.

Biochem/physiol Actions

DNA 合成、细胞核分裂和癌细胞的YZ剂。对革兰氏阳性菌、革兰氏阴性菌、抗酸杆菌有KJ性。

Caution

This vial contains 2 mg Mitomycin C ａnd 48 mg NaCl. Stock solutions should be filter sterilized ａnd stored at 2-8°C in the dark. Solutions at pH 6-9 can be stored at 0-5°C for up to a week, but if a precipitate forms, a fresh solution should be prepared - the precipitated solution has been proven toxic to cells.

Preparation Note

Mitomycin C is soluble in water at .5 mg/mL, with a pH of 6.0-7.5. It undergoes rapid degradation in acidic solutions with pH<6, ａnd is mostly likely to retain activity in solutions with a pH between 6-9.
