    Product Description

    bpV(pic) is a bisperoxovanadium (bpV) compound that inhibits several different protein tyrosine phosphatases (PTPs), with selectivity for PTEN (IC50 = 31 nM).1 It also inhibits the vascular endothelial PTP, PTP-β (IC50 = 12.7 μM), and PTP-1βB (IC50 = 61 μM).1 bpV(pic) is also known to be an insulin mimetic capable of activating the insulin receptor kinase of cultured hepatoma cells, stimulating lipogenesis in adipocytes, and inhibiting the dephosphorylation of autophosphorylated insulin receptors and epidermal growth factor receptors of rat liver endosomes.2 This product is also available as part of Cayman's Stem Cell Expansion Reagent Kit (SCB) (Item No. 502886).

    WARNING This product is not for human or veterinary use.
