analysis of these fractions by crossed immunoelectrophoresis revealed that the two components with slower electrophoretic mobility ( iat-iii2 and iat-iii3 ) had higher molecular size than iat-iii1 , that the concentration of iat-iii2 and iat-iii3 was significantly higher in serum , and that the high molecular weight components in plasma and serum were qualitatively identical .
