The Study of Human Ia‐Like Specificities Using Antibody Eluates from Human Lymphoblastoid Cell Lines

Abstract
Five sera from multiparous women were absorbed and eluted from the Daudi cell line devoid of HLA antigens. These eluates recognized a specificity, Ly‐Lil, of the Ly‐Li system. Further absorption of one eluate on Bjab or Raji cell line subdivided this specificity. Family studies showed that the five eluates from the Daudi cell line segregate into two distinct groups.
