Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the C-terminus of human Collagen XVII/COL17A1, which shares 83.3% and 91.3% amino acid (aa) sequence identity with mouse and rat Collagen XVII/COL17A1, respectively.
• Molecular weight context: reported MW: 125 kDa; calculated MW: nan
• Reactivity: Human
• Applications: WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

collagen type XVII alpha 1 chain. Collagen XVII, previously called BP180, is a transmembrane protein which plays a critical role in maintaining the linkage between the intracellular and the extracellular structural elements involved in epidermal adhesion. It is mapped to 10q25.1. This gene encodes the alpha chain of type XVII collagen. Unlike most collagens, collagen XVII is a transmembrane protein. Collagen XVII is a structural component of hemidesmosomes, multiprotein complexes at the dermal-epidermal basement membrane zone that mediate adhesion of keratinocytes to the underlying membrane. Mutations in this gene are associated with both generalized atrophic benign and junctional epidermolysis bullosa. Two homotrimeric forms of type XVII collagen exist. The full length form is the transmembrane protein. A soluble form, referred to as either ectodomain or LAD-1, is generated by proteolytic processing of the full length form. Functional note: May play a role in the integrity of hemidesmosome and the attachment of basal keratinocytes to the underlying basement membrane. The 120 kDa linear IgA disease antigen is an anchoring filament component involved in dermal-epidermal cohesion. Is the target of linear IgA bullous dermatosis autoantibodies. Reported localization: Hemidesmosome, Membrane, Single-pass type II membrane protein, Basement membrane. Expression/tissue context: Detected in skin. In the cornea, it is detected in the epithelial basement membrane, the epithelial cells, and at a lower level in stromal cells. Stratified squamous epithelia. Found in hemidesmosomes. Expressed in cornea, oral mucosa, esophagus, intestine, kidney collecting ducts, ureter, bladder, urethra and thymus but is absent in lung, blood vessels, skeletal muscle and nerves.

Research relevance and current trends

• Collagen: Researchers commonly examine how COL17A1 relates to this theme using model systems and orthogonal readouts.
• Cytoskeleton/ECM: Researchers commonly examine how COL17A1 relates to this theme using model systems and orthogonal readouts.
• ECM Proteins: Researchers commonly examine how COL17A1 relates to this theme using model systems and orthogonal readouts.

Common research applications

• Western blotting: compare relative COL17A1 levels across conditions; band patterns may reflect isoforms and processing.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
