Product Overview
This rabbit polyclonal antibody detects vitamin D-binding protein (gene GC) in human, mouse and rat samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 52.9 kDa, and the supplier reports an observed band at about 53 kDa.
Vitamin D-binding protein (GC, also called DBP or Gc-globulin) is a plasma protein made by the liver. It carries vitamin D and its metabolites in the blood, especially 25-hydroxyvitamin D, and also binds free actin released from damaged cells. It is studied in vitamin D biology, and variants of GC are common in human populations.

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): human placenta tissue, human A431 cells.
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): human liver cancer tissue, human lung cancer tissue, mouse liver tissue, human rectal cancer 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 human Vitamin D Binding protein fragment (Leu17–Glu256), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes vitamin D-binding protein as a secreted protein. Tissue expression noted by UniProt (human): Expressed in the liver. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
