CD138+ plasma cells or CD138- bone marrow mononuclear cells (BM-MNC) were cultured in RPMI 1640 medium supplemented with 10% FBS in the presence or absence of 10 nM bortezomib for 24 hours in U-bottom 96-well plates. Cells were washed with PBS and stained with fluorescently labeled anti-TRAIL receptor antibodies, TRAIL-R1 (DR-4-02), TRAIL-R2 (DR5-01-1), TRAIL-R3 (TRAIL-R2-02) and TRAIL-R4 (TRAIL-R4-01) (Thermo Scientific); anti-CD38 (HIT2, BD Biosciences, San Jose, CA) and anti-CD138 (MI15, BD Biosciences), additionally CD138- BM-MNC were stained with anti-CD45 (HI30, BD Biosciences) antibody 30 minutes on ice. The cells were then washed and resuspended in PBS at 4°C. Relative expression of each TRAIL receptor was normalized by MFI of corresponding isotype control.

Flow cytometry was performed on FACSCantoII and analysed by FACSDiva Software (BD Biosciences).
ROS production was evaluated in drug-treated NB cell lines by using CellROX Deep Red Reagent (C10422, Invitrogen) and measured by flow cytometry.
Whole-cell extracts were quantified by a bicinchoninic acid assay (Thermo Fisher Scientific), resolved on 8–10% SDS-PAGE and electroblotted. Filters were probed with primary antibodies followed by goat anti-mouse and HRP-conjugated rabbit anti-goat IgG (Jackson). The following antibodies for Western blotting were used: anti-p53 (FL-393) and anti-actin (I-19), purchased by Santa Cruz Biotechnology.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
