霉酚酸

Mycophenolic acid (MPA), produced by Penicillum brevi-compactum, is a selective inhibitor of inosine monphosphate dehydrogenase, thus inhibiting DNA synthesis in T and B lymphocytes. It has also been shown to act as an immunosuppressive agent, and as an inducer of monocyte differentiation and apoptosis in human lymphoid and monocytic cell lines. As a selection agent, MPA is used for transfected animal cells expressing the E. Coli gene for xanthine-guanine phosphoribosyl transferase, and is recommended for use at 25μg/mL.

作用方式：本品通过抑制细胞因子诱导的一氧化氮生成，抑制嘌呤核苷酸的早期生物合成，并作为 IMP 脱氢酶的特异性抑制剂发挥作用。

Mycophenolic acid is soluble in methanol at 50 mg/mL, yielding a colorless to faint yellow solution, as well as chloroform, dichloromethane, ethanol and .1 N NaOH. After reconstitution, the recommendation is to sterilize via filtration thorugh a 0.22 μm pore-size filter, aliquot, and freeze at -20°C.

As supplied, this product should be stored desiccated at 2-8°C, and is stable for 5 years when stored properly.
