Product Overview
Clone 9H9 is a mouse monoclonal antibody that recognizes collagen alpha-1(III) chain (gene COL3A1) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 138.6 kDa, and the supplier reports an observed band at about 180–190 kDa.
Collagen α1(III) chain (COL3A1) forms type III collagen, a fibrillar collagen that occurs with type I collagen in skin, blood vessels and hollow organs. It supports tissue elasticity and strength, and COL3A1 mutations cause vascular Ehlers-Danlos syndrome; it is also studied in wound healing and fibrosis.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
Samples with a confirmed band (WB): human placenta tissue, HeLa cells, rat heart tissue, mouse heart 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 1:5000, ECL detection.
Samples with confirmed staining (IHC): human intestinal cancer tissue, human mammary cancer tissue, human lung cancerr tissue, mouse intestine tissue, rat intestine 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 EDTA buffer (pH 8.0).
Immunogen
