Abstract
The value of the method of immune-adherence in studying by direct means the role of cation co-factors in human complement activation is shown. Clear evidence for the specificity of the Ca++ and Mg++ requirements is presented. Co++ partially replaced Mg++, but other divalent cations tested did not replace either Ca++ or Mg++. The optimal concentrations of cations useful in the titrations of human complement by immune-adherence are suggested to be 0.0001 [image] Ca++ and 0.001 [image] Mg++.
