[Detection of an antigen, associated with cells during the blast crisis of chronic myeloleukemia, in a cytotoxic test using xenogenic antibodies].
The immune antimyeloblast serum (AMS) was obtained from horses immunized with white blood cells from patients suffering from chronic myeloid leukemia (CML) at the blast crisis stage; the serum was completely absorbed with normal red blood cells and white blood cells (WBC). The absorbed antiserum remained cytotoxic to blast cells from 20 of 42 patients with CML at the blast crisis stage. AMS failed to react with the WBC from patients with CML in its chronic phase, and from patients with other types of leukemia Morphological studies indicated a possibility of identification of the antigen associated with myeloblasts from the blood of patients with CML blast crisis, by means to AMS.
