Summary
An antiserum was raised in rabbits to extracts of a pool of acute myelogenous leukemia cells. The immunization protocol used (antibody feedback) gave rise to antisera with marked specificity for AML extracts. After absorption, the antiserum demonstrated essentially no reactivity with cell extracts from 12 individual normal peripheral blood samples, while it reacted positively with 16 individual extracts from AML cells. Reactivity was assayed by the enzyme-linked immunosorbent assay (ELISA). The antiserum was not reactive with extracts from normal PHA-induced blast cells, with extracts of bone marrow cells from six individuals, or with three individual extracts of chronic lymphocytic leukemia (CLL) blast cells. These data indicate that this antiserum is detecting an antigen that is common to AML cells but may not be common to other blast cells.
