Tested Applications

• Positive WB detected in: A431 cells, mouse skin tissue
• Positive IHC detected in: rat skin tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF/ICC detected in: A431 cells, HaCaT cells

Recommended dilution

• Western Blot (WB): WB : 1:500-1:3000
• Immunohistochemistry (IHC): IHC : 1:50-1:500
• Immunofluorescence (IF)/ICC: IF/ICC : 1:200-1:800

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Collagen alpha-1(XVII) chain, also termed 180-kDa bullous pemphigoid antigen (BP180), is a type II transmembrane glycoprotein with a collagenous carboxyl-terminal extracellular domain and a noncollagenous amino-terminal cytoplasmic domain. High expression of COL17A1 has also been identified as a marker of human esophageal quiescent stem/progenitor cells (PMID: 35709398, 9545306). As a structural component of the hemidesmosome, COL17A1 is not only present as the full-length 180 kDa transmembrane form, but also as a cleaved 120 kDa soluble form that is further processed to a 97 kDa form (PMID: 113594550).
