Product Overview
This rabbit polyclonal antibody recognizes cathepsin G (gene Ctsg) in mouse and rat samples and is validated for Western blot. The predicted molecular weight is 29.1 kDa, and the supplier reports an observed band at about 29 kDa.
Cathepsin G (CTSG) is a serine protease stored in the azurophil granules of neutrophils, with both trypsin-like and chymotrypsin-like activity. Released at sites of inflammation, it kills bacteria, remodels tissue, cleaves protease-activated receptors on platelets and other cells, and processes cytokines such as IL-36γ. It is studied in neutrophil biology, inflammation and host defense.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat) |
|---|
Samples with a confirmed band (WB): rat liver tissue, rat kidney tissue, mouse liver tissue, mouse kidney tissue, mouse HEPA1–6 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 overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Recombinant mouse Cathepsin G fragment (Ile21–Thr261), expressed in E. coli. Sequence identity with the human ortholog: 70.2%.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes cathepsin G as secreted and also located in the cell membrane, cytoplasmic granule and cytoplasm. Tissue expression noted by UniProt (mouse): In adult, detected only in bone marrow where expression is restricted to a small population of early myeloid cells. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
