IHC-Fr Use at an assay dependent concentration.


  • FunctionFactor XIII is activated by thrombin and calcium ion to a transglutaminase that catalyzes the formation of gamma-glutamyl-epsilon-lysine cross-links between fibrin chains, thus stabilizing the fibrin clot. Also cross-link alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin.
  • Involvement in diseaseDefects in F13A1 are the cause of factor XIII subunit A deficiency (FA13AD) [MIM:613225]. FA13AD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.
  • Sequence similaritiesBelongs to the transglutaminase superfamily. Transglutaminase family.
  • Post-translational
    The activation peptide is released by thrombin.
  • Cellular localizationCytoplasm. Secreted. Secreted into the blood plasma. Cytoplasmic in most tissues, but also secreted in the blood plasma.

  • ab4057 staining formalin fixed paraffin-embedded human bowel tumour tissue sections.  The sample was subjected to heat mediated antigen retrieval in citrate buffer (pH 6.0) and blocked with 10% srum for 1 hour at 24°C, prior to incubation with the primary antibody (diluted 1/100 in milk) for 12 hours at 4°C.  A biotinylated goat anti-rabbit antibody was used as the secondary.
