Anti-PTPRE Antibody

Raised in rabbit and supplied by Antibodies.com as a 100 µl aliquot at 1 mg/ml, this unconjugated polyclonal reagent targets the receptor-type protein tyrosine phosphatase PTPRE for immunodetection in human-derived samples. The antibody is validated for Western blot and immunohistochemistry workflows, where it recognizes endogenous PTPRE in lysates and fixed tissue sections. The formulation uses PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant, permitting storage at standard refrigerator temperatures while preserving activity across freeze-thaw cycles. As a polyclonal reagent, the preparation contains a heterogeneous pool of IgG molecules directed against multiple epitopes on PTPRE, which can improve signal robustness over monoclonal alternatives when the target is partially degraded or post-translationally modified. PTPRE catalyzes dephosphorylation of tyrosine residues on signaling substrates and has been implicated in studies of insulin receptor regulation, neuronal differentiation, and tumor cell behavior, supporting laboratory work on receptor phosphatase signaling in cancer, metabolic, and neuroscience research.
