Product Overview
This rabbit polyclonal antibody detects histidine-rich glycoprotein (gene HRG) in human samples and is validated for IHC and Western blot. The predicted molecular weight is 59.6 kDa, and the supplier reports an observed band at about 60 kDa.
Histidine-rich glycoprotein (HRG) is an abundant plasma protein made by the liver. It binds many ligands, including heparin, heme, zinc and plasminogen, and through these interactions it modulates coagulation, fibrinolysis, angiogenesis and immune responses, so it is studied in blood biology and inflammation.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human) |
Samples with a confirmed band (WB): human placenta tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (IHC): human intestinal cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Recombinant human HRG fragment (Val19–Val200), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 71% and 69%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes histidine-rich glycoprotein as a secreted protein. Tissue expression noted by UniProt (human): Expressed in macrophages and in malignant cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
