Actinomycin D, Streptomyces sp.

Anti-neoplastic antibiotic. Inhibits DNA-primed RNA polymerase by complexing with DNA via deoxyguanosine residues. At higher concentrations, DNA polymerase is inhibited. Also acts as a competitive inhibitor of serine proteases. Inhibits cell growth and colony formation in synchronized HeLa cells. Induces apoptosis in many cell lines. However, actinomycin D has also been shown to suppress etoposide-induced apoptosis in PC12 cells. Note: 1 set = 20 x 200 µg.

Antineoplastic antibiotic. Inhibits DNA-primed RNA polymerase by complexing with DNA via deoxyguanosine residues. A DNA-intercalator with growth inhibitory activity against certain leukemias and sarcomas. At higher concentrations, DNA polymerase is inhibited. Inhibits cell growth and colony formation in synchronized HeLa cells. A potent inducer of apoptosis in many cell lines; however, actinomycin D has also been shown to suppress programmed cell death of PC12 cells induced by etoposide, an inhibitor of topoisomerase II. Acts as a competitive inhibitor of serine protease from microorganisms. The growth of S. aureus is inhibited by 0.25-0.75 µg/ml, whereas a concentration of 100 µg/ml is required to inhibit E. coli due to permeability differences. Heat resistant and stable between pH 2 and 11; decomposed by strong acids and bases. λ_max 441 nm ±2 nm. Note: 1 set = 20 vials x 200 µg.

Stability: heat resistant and stable between pH 2 and 11. Decomposed by strong acids and bases.
