| Cell lines | CLL cells |
| Preparation method | To evaluate the effect of BCR stimulation on CLL cell viability, CLL cells (107/mL) were incubated in complete RPMI medium (control) or in complete medium supplemented with 10 μg/mL anti-IgM (polyclonal goat F(ab′)2 fragments to human IgM [MP Biomedicals] at 37°C in 5% CO2). After 24 and 48 hours, CLL cell viability was measured by analysis of mitochondrial transmembrane potential by 3,3 dihexyloxocarbocyanine iodine (DiOC6; Invitrogen-Molecular Probes) and cell membrane permeability to propidium iodide (PI; Molecular Probes), as described.13 Briefly, 200 μL cell suspension was collected at the indicated time points and transferred to fluorescence-activated cell sorter tubes containing 200 μL of 60 nM DiOC6 and 2 μg/mL PI in RPMI with 0.5% bovine serum albumin. Cells were then incubated at 37°C for 15 minutes and analyzed within 30 minutes by flow cytometry on a FACSCalibur (BD Biosciences). |
