title: [Isolation and characteristics of IKO-GM-1 monoclonal antibodies].
abstract: The hybridoma clone IKO-GM-1 was obtained as a result of fusion of P3X63Ag8.653 cells with splenocytes of BALB/c mice with the aid of 50% polyethyleneglycol. Antigen demonstrated by antibodies IKO-GM-1 expressed on 100% polymorphonuclear neutrophils, 54.4 +/- 3.1% monocytes, 25.9 +/- 2.4% mononuclears of healthy subjects' blood, on 11.1 +/- 1.0% T lymphocytes, on 14.6 +/- 1.6% T lymphocytes bearing Fc-receptor for IgG, on 49.3 +/- 8.2% enriched population of B lymphocytes and O cells. The treatment of healthy donors' mononuclears with antibodies IKO-GM-1 and complement blocked EK cellular activity against Molt-2 cells but not against K-562 cells. Antigen demonstrated by MAT IKO-GM-1 did not express on the colony-forming granulocyte or macrophagal cells. Antigen expressed on blast cells of patients with AMonoL, on those in part of patients with AML and AMML, on leukocytes of patients with chronic ML, on monocytes of a patient with chronic MonoL. Antigen was absent from blast cells of patients with ALL, LSA, on lymphocytes of patients with ChLL.
