Determination of C1R Types in Bloodstains
Genetic polymorphism of the C1R subcomponent was first discovered by Kamboh and Ferrell (1986). Using isoelectric focusing and immunoblotting, they described 2 common alleles C1R*1 and C1R*2 in native plasma samples from US whites and US blacks. Besides these 2 common alleles, several further variant alleles have been detected in a variety of ethnic groups by treating plasma samples with neuraminidase (Kamboh et al. 1988, 1989; Nakamura et al. 1988).
