Abstract: | Monoclonal antibody 41H.16 was produced by using the hybridoma methodology in the mouse system with cells from a patient with hairy cell leukemia as the immunogen. This antibody reacts with the majority of Slg+ cells in the peripheral blood and with all B lymphoblastoid cell lines. Reactivity with conventional Ig determinants, Fc or C3 receptors, has been excluded. The antibody reacted with cells from 68 patients with CLL but showed no reactivity with cells in 69 specimens from patients with non-T, non-B ALL. The apparent m.w. of the antigen detected by this antibody is approximately 39,000. |
