Abstract
A new polymorphism of coagulation factor XIII was observed in both platelets and plasma by using a fluorescent technique for the localization of transglutaminase activity after electrophoresis on thin layer agarose gels. The electrophoretic pattern was that of a dimeric protein. Homozygotes gave a single band, while heterozygotes had a 3 banded pattern. The polymorphism was due to variation of the A subunit. Data from Australian blood donors indicate that the A subunit of factor XIII has an autosomal locus.
