Complement-mediated lysis of lymphoma lines by rituximab.
The indicated cell lines were incubated at 1 × 106/mL in the presence (closed squares) or the absence (open squares) of 2 μg/mL rituximab and increasing concentrations of NHS. Percentage cell lysis was measured after 1 hour at 37°C by cell count with trypan blue. The data are representative of at least 3 different experiments.
