    Product Description

    Pitstop2 is an inhibitor of the interaction between the clathrin terminal domain and amphiphysin (IC50 = 12 μM).1 It inhibits clathrin-mediated transferrin uptake in HeLa and U2OS cells (IC50s = 12-15 and 9.7 μM, respectively). Pitstop2 inhibits HIV-1 entry and infectivity in HeLa reporter cell lines. It also inhibits clathrin-independent endocytosis of CD44, CD98, and CD147 in HeLa cells.2

    WARNING This product is not for human or veterinary use.
