Peptides having the structuren H-A1-A2-A3-A4-Gin-A6-Lys-Val-A9-A10-NH2 (I> in whichn A1 is Val or Leu,n A2 is Gly or Ser,n A3 is Pro or Hyp,n A4 is Gly or Ser,n A6 is Gly or Ser,n A9 is Leu or Ile andn A10 is Gly or Ala,n and their salts act as substrates for blood coagulation factor XIII and can be used to assay this enzyme and to detect reactions in which activated coagulation factor XIII is produced, consumed or inhibited. |
