Product Overview
This rabbit polyclonal antibody detects DNA-binding protein inhibitor ID-1 (gene Id1) in mouse and rat samples and is validated for Western blot and ELISA. The predicted molecular weight is 17.9 kDa, and the supplier reports an observed band at about 25 kDa.
ID1 (inhibitor of DNA binding 1) is a helix-loop-helix protein that lacks a DNA-binding region. It pairs with basic helix-loop-helix transcription factors and prevents them from binding DNA, thereby holding back differentiation and favoring proliferation, and it is studied in stem cells, angiogenesis, BMP signaling and cancer.

Validated Applications
| Western blot | 0.1–0.25 µg/mL (Mouse, Rat) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat pancreas tissue, mouse pancreas 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, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.25 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant mouse Id1 fragment (Cys16–Ile168), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places DNA-binding protein inhibitor ID-1 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
