Product Overview
This rabbit polyclonal antibody detects insulin-like growth factor 1 (gene IGF1) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 21.8 kDa, and the supplier reports an observed band at about 50 kDa.
Insulin-like growth factor 1 (IGF-1) is a peptide hormone, produced mainly by the liver under growth hormone control, that is structurally related to insulin. Acting through the IGF-1 receptor, it promotes cell growth, proliferation and survival and mediates many effects of growth hormone on body growth and metabolism.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Rat, Mouse) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human) |
Samples with confirmed staining (IHC): human mammary cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Synthetic peptide from the middle region of human IGF-1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes insulin-like growth factor 1 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
