Product Overview
This rabbit polyclonal antibody detects collagen alpha-1(XVII) chain (gene COL17A1) in human samples and is validated for Western blot. The predicted molecular weight is 150.4 kDa, and the supplier reports an observed band at about 125 kDa.
Collagen XVII (COL17A1, also known as BP180) is a transmembrane collagen of hemidesmosomes that anchors basal keratinocytes to the underlying basement membrane. It is an autoantigen in bullous pemphigoid, and its shed ectodomain is a target in linear IgA disease, making it central to skin adhesion research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|
Samples with a confirmed band (WB): human HeLa 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
Synthetic peptide from the C-terminal region of human collagen XVII/COL17A1. Sequence identity with the mouse and rat orthologs: 83.3% and 91.3%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places collagen alpha-1(XVII) chain in the cell junction and membrane. Tissue expression noted by UniProt (human): Detected in skin. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
