Product Overview
This rabbit polyclonal antibody targets insulin-like growth factor-binding protein 1 (gene Igfbp1) in mouse and rat samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 29.6 kDa, and the supplier reports an observed band at about 30 kDa.
IGFBP-1 is a secreted insulin-like growth factor binding protein produced mainly by the liver and by decidualized endometrium. It binds IGF-1 and IGF-2 and controls their access to receptors, with levels acutely regulated by insulin and nutritional state, and it can also signal through integrin α5β1 to promote cell migration.

Samples with a confirmed band (WB): rat liver tissue, 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 overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with confirmed staining (IHC): mouse liver tissue, mouse pancreas tissue, rat liver tissue, rat pancreas 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 IGFBP1 fragment (Ala26–Asn272), expressed in E. coli. Sequence identity with the human and rat orthologs: 68.4% and 95.5%, respectively.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes insulin-like growth factor-binding protein 1 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
