Western blot analysis of TRAIL receptor expression in MM and NHL B-cell lines.

Western blot analysis for DR4 and DR5 death-signaling and DcR1 and DcR2 “decoy” TRAIL receptors was performed in lysates derived from 10 MM cell lines (MM-AS, MM-SV, MM-1S, U266, RPMI-8226/S, S6B45, OCI My-5, ARH-77, HS Sultan, and IM-9) and 2 NHL B-cell lines (DHL-4 and DHL-10). SK-N-MC Ewing sarcoma cells served as a positive control. Tubulin detection was used to confirm equal protein loading.
