Anti-IRS1 Antibody, clone 58-10C-31, rabbit monoclonal

32160702

NA.41

IRS1 (Insulin Receptor Substrate 1) transmits insulin signals via metabolic and mitogenic pathways. It is heavily phosphorylated on both serine and tyrosine residues. These phosphorylated tyrosines enable IRS to act as a docking protein that binds SH2 domains of such proteins as PI3 Kinase (phosphatidylinositol 3-kinase) and GRB2, resulting in activation. Over expression and phosphorylation of serine is associated with insulin resistance and breast cancer.

Antibody recognizes the C-terminus of IRS1.

Epitope: C-terminus
KLH- conjugated - linear peptide corresponding to the C-terminus of rat IRS1.

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
