Frequently Asked Questions

Frequently Asked Questions are available for this Product.

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抑制剂。对革兰氏阳性菌、革兰氏阴性菌、抗酸杆菌有抗菌性。

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.

Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

Actinomycin D is an antineoplastic antibiotic that inhibits cell proliferation with wide-ranging applications ranging from a selection agent in cell culture, use in studies of suppressing HIV-replication and programmed cell death of PC12 cells, and as an antibiotic in treatment of various malignant neoplasms, including Wilm′s tumour and the sarcomas. Recommended for us in cell culture applications at 1μg/mL.

Caution

This product is hygroscopic and light-sensitive. If stored protected from light and moisture at 2-8°C, it remains unchanged, by HPLC testing, for at least 15 months. Unused dilute solutions of Actinomycin D are extremely sensitive to light and tend to adsorb to plastic and glass and should be discarded. However, frozen aliquots of concentrated stock solution are stable for at least a month.

包装：2, 5, 10, 25 mg in glass bottle

Preparation Note

Actinomycin D is sold as red, shiny crystals and is soluble in acetonitrilie or acetone at 10 mg/mL and in DMSO at a minimum of 1 mg/mL. Some references also show slight solubility in water of 0.5 mg/mL.

Biochem/physiol Actions

Actinomycin D inhibits the proliferation of cells by forming a stable complex with double-stranded DNA, inhibiting DNA-primed RNA synthesis and causing single-stranded breaks in DNA. It has been shown to be an inhibitor of the minus-strand transfer step in reverse transcriptase.
