Research Products International Corp Mitomycin C, 5 MG

Mitomycin C is a potent antitumor antibiotic. It is derived from Streptomyces caespitosus and exhibits strong cytotoxic properties. It works by cross-linking DNA, inhibiting DNA synthesis, and inducing cell death. Mitomycin C finds applications in molecular biology and cell biology research. It is frequently employed as a DNA cross-linking agent in studies involving DNA damage and repair mechanisms.

Researchers use Mitomycin C to induce DNA adduct formation and study the cellular response to DNA damage. One notable feature of Mitomycin C is its ability to induce DNA cross-links in both dividing and non-dividing cells, making it useful for investigating cellular processes beyond actively dividing cells.

WARNING! This product can expose you to Mitomycin-C, a chemical which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov.
