Anti-BPA-2 antibodies are used in antigen-specific immunodetection in biological samples. The target BPA-2 is a known alias name of the protein collagen type XVII alpha 1 chain, encoded by the COL17A1 gene in humans. This 1497-amino acid residue protein is believed to 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. It is localized to the extracellular matrix of the cell and features glycosylated, cleaved and phosphorylated post-translational modifications. In terms of tissue expression, it is notably expressed in skin. Other synonyms for BPA-2 include BA16H23.2, BP180, and BPA-2. Indicated applications for BPA-2 antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
