moreover , the absorption of polyspecific heterologous antiserum to crude hodgkin 's extracts , which contains antibodies reacting with f-antigen , the slower migrating s-antigen , and a third specificity present in lysates of normal peripheral blood lymphocytes ( pl-antigen ) , with ferritin , removed only anti-f activity , thus distinguishing the s- and pl-antigens from ferritin .
