Cell death induction by the combination of rituximab and normal human AB serum.
Cells from a representative CD20++ patient with follicular lymphoma (FL) were incubated in the presence or absence of 50 μg/mL rituximab and 10% AB (R+AB) for 24 hours and analyzed by flow cytometry. (A) Flow cytometric plots showing FSC/SSC pattern. (B) Flow cytometric plots showing annexin V binding. (C) Histogram showing mitochondrial transmembrane potential after staining with DiOC6[3].
