Immunocytochemical methods using monoclonal antibodies and lectins in the diagnosis of lymphoblastic leukemia in children

: ICO, IPO, LT monoclonal antibodies and lectins were used to study blood cells in 18 children with acute lymphoblastic leukemia (ALL). The immunological phenotype has been characterized, and two cytological variants of ALL of T-cell nature, and four variants of ALL of B-cell origin have been distinguished, differing by the degree of blast cell maturity.
