Anti-IRS-1 (Y632) Antibody

Affinity-purified polyclonal reagent targeting the tyrosine-632 phosphorylated epitope of insulin receptor substrate 1 (IRS-1), a key adaptor in insulin and IGF-1 receptor signaling cascades. Antibodies.com supplies this unconjugated Primary Antibody as 100 µl at 1 mg/ml in phosphate buffered saline with 0.05% sodium azide at approximately pH 7.2, giving researchers flexibility to pair it with their preferred detection chemistry. Validated for immunohistochemistry on human, mouse, and rat tissue sections, the polyclonal host recognition profile captures multiple epitopes around the phospho-Y632 residue, supporting studies of metabolic disease, insulin resistance, and growth factor pathway activation. Aliquoting upon receipt is recommended to minimize repeated freeze-thaw cycles, and the azide preservative maintains reagent sterility during routine handling.
