Product Overview
This rabbit polyclonal antibody recognizes insulin-like growth factor 1 receptor (gene Igf1r) in mouse and rat samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 155.8 kDa, and the supplier reports an observed band at about 155 kDa.
The IGF-1 receptor (IGF1R) is a receptor tyrosine kinase that binds IGF-1 with high affinity and IGF-2 and insulin more weakly. Ligand binding triggers autophosphorylation and recruitment of adaptors such as IRS proteins and SHC, activating the PI3K-AKT and MAPK pathways that drive growth and survival, which makes IGF1R a focus of growth and cancer research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with confirmed staining (IHC): mouse small intestine tissue, mouse kidney tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Immunogen
Recombinant mouse IGF1 Receptor fragment (Glu31–Lys257), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places insulin-like growth factor 1 receptor in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
