Scientific Data Images for Human/Mouse/Rat IRS1 Antibody

Detection of Human, Mouse, and Rat IRS1 by Western Blot.

Western blot shows lysates of MCF-7 human breast cancer cell line, HepG2 human hepatocellular carcinoma cell line, C2C12 mouse myoblast cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat IRS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3978) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IRS1 at approximately 170 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

IRS1 in Human Liver Cancer Tissue.

IRS1 was detected in immersion fixed paraffin-embedded sections of human liver cancer tissue using Goat Anti-Human/Mouse/Rat IRS1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3978) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm.

Formulation, Preparation, and Storage

Purification

Antigen Affinity-purified

Reconstitution

Reconstitute at 0.2 mg/mL in sterile PBS. For liquid material, refer to CoA for concentration.

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Shipping

Lyophilized product is shipped at ambient temperature. Liquid small pack size (-SP) is shipped with polar packs. Upon receipt, store immediately at the temperature recommended below.

Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

12 months from date of receipt, -20 to -70 °C as supplied.
1 month, 2 to 8 °C under sterile conditions after reconstitution.
6 months, -20 to -70 °C under sterile conditions after reconstitution.

Calculators

The reconstitution calculator allows you to quickly calculate the volume of a reagent to reconstitute your vial. Simply enter the mass of reagent and the target concentration and the calculator will determine the rest.

Background: IRS1

IRS1 (Insulin Receptor Substrate 1) is a cytoplasmic protein that participates in the insulin signaling pathway. It is phosphorylated by the insulin receptor upon binding of insulin and subsequently associates with several SH2-domain-containing proteins.
