    生物活性

    Bafilomycin A1 (BafA1) is a specific and reversible inhibitor of vacuolar H+-ATPase (V-ATPase) with IC50 values of 4-400 nmol/mg. Bafilomycin A1, a macrolide antibiotic, is also used as an autophagy inhibitor at the late stage. Bafilomycin A1 blocks autophagosome-lysosome fusion and inhibits acidification and protein degradation in lysosomes of cultured cells. Bafilomycin A1 induces apoptosis[1][2][3].

    [2]

    Cells are harvested using 0.05% trypsin and suspended in culture medium containing 10% FCS, and 200 µL suspension is added to each well of a 96-well plate. Cells are cultured for 20 h for adhesion. Bafilomycin A1 is added to the wells at the final concentrations of 200, 400 and 800 nM, in triplicate. At 24, 48 and 72 h, 20 µl WST-1 is added to the cells. Following incubation at 37°C for 4 h, the plates are read to determine the optical density (OD) at 435 nm with 675 nm reference using a spectrophotometer[2].

Tumor size is measured and tumor volume doubling time is calculated[4].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
