Electroporation of siRNA into CLL cells was performed using Amaxa Human B-cell Nucleofection Kit (Amaxa, Cologne, Germany). 1x107 PBMCs were mixed with 100 μL of Amaxa B-cell nucleofector solution, and 2 μg of siRNA was nucleofected using program X-005 [29 (link)]. Transfection efficiency, assessed by transfection with 2 μg pMaxGFP plasmid, was 30–60% with cell viability of 50–80% at 24 hours. siRNA oligos were synthesized by Dharmacon (Lafayette, CO). Sense strand against human ASK1: GCUCGUAAUUUAUACACUGUU.
