Factor XIIIa Antibody (SPM180) Summary

• Description: 200ug/ml of antibody purified from Bioreactor Concentrate by Protein A or G. Prepared in 10 mM PBS with 0.05% BSA & 0.05% azide. Also available WITHOUT BSA & azide at 1.0 mg/ml. (NBP2-54480)
  
  Antibody with azide - store at 2 to 8C. Antibody without azide - store at -20 to -80C.
• Immunogen: Recombinant fragment of human Factor XIIIa protein (aa46-181) (exact sequence is proprietary) (Uniprot: P00488)
• Localization: Cytoplasmic and Secreted
• Specificity: It recognizes a protein of 83kDa, which is identified as Factor XIIIa. It has been identified in platelets, megakaryocytes, and fibroblast-like mesenchymal or histiocytic cells in the placenta, uterus, and prostate, monocytes and macrophages and dermal dendritic cells. Anti-factor XIIIa has been found to be useful in differentiating between dermatofibroma (almost all cases are positive), dermatofibrosarcoma protuberans (-/+) and desmoplastic malignant melanoma (-). Anti-factor XIIIa positivity is also seen in capillary hemagioblastoma, hemangioendothelioma, hemangiopericytoma, xanthogranuloma, xanthoma, hepatocellular carcinoma, glomus tumor, and meningioma.
• Isotype: IgG2b Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: F13A1
• Purity: Protein A or G purified

Applications/Dilutions

• Dilutions:
  • ELISA 2-4 ug/ml
  • Flow Cytometry 1-2 ug/million cells
  • Immunocytochemistry/ Immunofluorescence 1-2 ug/ml
  • Immunohistochemistry
  • Immunohistochemistry-Frozen
  • Immunohistochemistry-Paraffin 1-2 ug/ml
  • Western Blot 1-2 ug/ml
• Application Notes: ELISA: Use Ab at 2-4ug/ml for coating. Order Ab without BSA.
  Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 min at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
  Optimal dilution for a specific application should be determined.
• Theoretical MW: 83 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Factor XIII is a beta globulin found in plasma and is composed of two subunits. Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade. Factor XIII A is the catalytic subunit and is a dimmer of molecular weight 160kDa. The B subunits do not have enzymatic activity and may serve as a plasma carrier molecules. Platelet factor XIII is comprised only of 2 A subunits, which are identical to those of plasma origin. Upon activation by the cleavage of the activation peptide by thrombin and in the presence of calcium ion, the plasma factor XIII dissociates its B subunits and yields the same active enzyme, factor XIII A, as platelet factor XIII. This enzyme acts as a transglutaminase to catalyze the formation of gamma-glutamyl-epsilon-lysine crosslinking between fibrin molecules, thus stabilizing the fibrin clot. It also crosslinks alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin. Factor XIII deficiency is classified into two categories: type I deficiency, characterized by the lack of both the A and B subunits; and type II deficiency, characterized by the lack of the A subunit alone. These defects can result in a lifelong bleeding tendency, defective wound healing, and habitual abortion. Factor XIII A is a dermal dendrocyte marker and shows variable reaction with these types of tumors. It can be used for histiocytic phenotyping and has been reported to mark capillary hemangiomas and tumors of the central nervous system.
