Human Collagen XIII  alpha 1 Antibody

  
  • Species Reactivity
    Human
  • Specificity
    Detects human Collagen XIII in direct ELISAs and Western blots. In direct ELISAs, approximately 40% cross-reactivity with recombinant mouse COL13A1 and less than 1% cross-reactivity with recombinant human (rh) COL23A1 and rhCOL25A1 is observed.

Data Examples
Detection of Human Collagen XIII alpha 1 by Western Blot. Western blot shows lysates of HUVEC human umbilical vein endothelial cells. PVDF Membrane was probed with 1 µg/mL of Human Collagen XIII alpha 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6346) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Two specific bands were detected for Collagen XIII a1 at approximately 100 and 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Collagen XIII alpha 1
COL13A1 (collagen 13-alpha 1) is a 95 kDa member of the transmembrane group of the collagen family of proteins. It is a type II transmembrane glycoprotein that is expressed by multiple cell types, including fibroblasts, endothelial cells, and cardiac muscle. COL13A1 forms disulfide-linked homotrimers and participates in cell adhesion by binding to the integrin alpha 1 subunit, nidogen-2, and fibronectin. Human COL13A1 is 717 amino acids (aa) in length (SwissProt #:Q5TAT6). It has an N‑terminal 44 amino acid cytoplasmic region plus a 656 amino acid extracellular domain (ECD) (aa 62-717). The ECD contains four non-collagenous (NC) regions (aa 1‑121, 217-269, 442-463, and 700-717) interspersed among three collagenous (COL) domains (aa 122-216, 270-441, and 464-699). Multiple splice forms exist and typically involve deletions of 12-30 aa between aa 220-705. Proteolytic cleavage after Arg108 generates an 85-90 kDa soluble form. Over aa 109-668 (based on a human isoform [NP_542992} that shows a deletion of aa 239-260, 551-565, and 616-627), human COL13A1 shares 91% aa sequence identity with mouse COL13A1.
