Anti-OB-R binds to normal mononuclear cells, but not to leukemic cells.

Bone marrow cells from healthy BN rats (A) and leukemic rats (B) were incubated with anti–OB-R linked to a secondary fluorescent antibody before analysis with flow cytometry. An irrelevant antibody was used as a negative control. Data are from one experiment and representative of 7 other experiments.
