    Product Description

    Protein tyrosine phosphatase 1B (PTP1B) has critical roles in cell signaling relevant to diabetes, obesity, and cancer.1,2 PTP1B inhibitor is a cell-permeable allosteric inhibitor of PTP1B (IC50s = 4 and 8 µM for 403 and 298 residue PTP1B forms, respectively).3 It binds reversibly and non-competitively, altering the conformation of the catalytic pocket.3,4 PTP1B inhibitor selectively increases the phosphorylation of the insulin receptor, insulin receptor substrate 1, and Akt, mimicking the action of insulin.3

    WARNING This product is not for human or veterinary use.
