The Electrophoretic Analysis of the Third Component of Complement (C3) in Dried Bloodstains
The polymorphic serum protein C3, which is the third component of the classical complement system, has been analyzed by agarose gel electrophoresis and immunofixation. It is sufficiently stable that phenotyping can be performed from dried bloodstains maintained at room temperature for at least two weeks or kept frozen for at least one month. Because its rate of migration differs from that of group specific component (Gc) in Tris-glycine buffer, both genetic markers can be simultaneously phenotyped.
