Human F13A1 / Factor XIIIa. The defined antibody reactivity is restricted to Factor XIII and FXIIIa in plasma and to platelet FXIII. As tested at the level of sensitivity of immunoprecipitation techniques a single precipitin line is obtained in bidimensional electrophoresis, immunoelectrophoresis and double radial immunodiffusion (Ouchterlony) which shows a reaction of full identity with A subunits of FXIII. No reaction is obtained with FXIII-depleted plasma and with B subunits. Cross-reactivity The antiserum does not cross-react with any other human plasma proteins as tested in gel-diffusion techniques. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.
Usage: This product is intended for use in precipitating techniques as electroimmunodiffusion, immunoelectrophoresis and single and double radial immunodiffusion (Mancini, Ouchterlony). To prepare an adsorbent for immunoaffinity purification of FXIII. If used in more sensitive test procedures or as catching or detection antibody in solid phase immunoassays specificity controls should always be include. Increase in plasma FXIII has been observed in type IV hyperlipoproteinaemia and in combined hyperlipodaemia. Congenital and acquired FXIII deficiencies have also been reported. In some cases of myeloma, inhibition of FXIII activity by the paraproteins may occur.
