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

Mode of Action: This product is an alkylating agent that specifically targets the guanine nucleoside sequence 5′-CpG-3′. It inhibits DNA synthesis by covalently reacting with DNA, forming crosslinks between complementary strands of DNA. This interaction prevents separation of complementary DNA strands, inhibiting DNA replication.

Antimicrobial Spectrum: Mitomycin C has strong antitumor activity, especially against Ehrlich ascites tumor cells, and strong bactericidal action against gram-positive and gram-negative bacteria.

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

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis. These documents are located on the product detail page under Useful Links & Tools. Click on the following link to search for a Certificate of Analysis. Please click the following link to see the details on our Product Dating Information.
How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
How do I store a stock solution of Mitomycin C, Product M0503?
Generally, solutions at pH 6–9 can be stored at 0–5 °C for up to a week, and possibly much longer. If a precipitate forms, a fresh solution should be prepared. The precipitated solution has proven to be toxic to cells. A stock solution should also be stored in the dark since mitomycin C is readily decomposed by light. Solutions should not be frozen, since a precipitate is likely to form.
What is the difference between Mitomycin C Product No. M0503 and M4287?
The difference between Product Nos. M0503 and M4287 is that Product No. M4287 has been tested on cells. A feeder layer is treated with media containing 10 μg/mL mitomycin C for 3 hours at 37°C to block replication.  
How do I use Mitomycin C, Product M0503, to block replication?
Cell functions that require cellular division are abolished by treatment with mitomycin C (causes DNA crosslinking). This can be used to treat cells for feeder layers, for mixed lymphocyte reactions and for removal of fibroblasts from mixed cell cultures. Mitomycin is used at 25 μg/mL to treat cells at 1 - 6 × 107 cells/mL. Cells are treated for 25 minutes at 37 °C. Selected Methods in Cellular Immunology, Michell, BB, and Shiigi, SM, Eds., WH Freeman and Co., New York, 1980, p. 240.
Why does Mitomycin C, Product M0503, contain  NaCl?
Sodium chloride is added to mitomycin C to increase solubility and solution stability.
Is Mitomycin C, Product M0503, light sensitive?
Mitomycin C is light sensitive only when in solution and not as a powder.
How do I find price and availability?
There are several ways to find pricing and availability for our products.  Once you log onto our website, you will find the price and availability displayed on the product detail page.
