A trial of utilizing antibodies as carriers of alkylating agents. I. Influence of cyclophosphamide and chlormethine on antigenic properties of serum proteins.
Electrophorograms of human and rabbit sera before and after incubation with various concentrations of cyclophosphamide and chlormethine (Nitrogranulogen) were compared. Sera of rabbits injected with chlormethine and cyclophosphamide in therapeutic doses for humans were examined for antibodies reacting with homologous and antologous gamma-globulins. Immunoelectrophorograms of sera incubated with both alkylating agents differed from those of preincubation sera with regard to number and intensity of precipitin lines. The changes in electrophorograms were related to the type and concentration of alkylating agent. No antibodies to homologous or autologous serum antigens of rabbits treated with chlormethine or cyclophosphamide were found.
