Check if the same lab product or an alternative is used in the 5 most similar protocols
In order to further explore the role of Circ-SMARCA5 in MM etiology, cells experiments were subsequently performed. Wild type MM cell lines (NCI-H929, RPMI8226, U226, OPM2 and JJN3) were purchased from Chinese Academy of Sciences (Beijing, China) or kindly given by Shanghai Jiaotong University (Shanghai, China), and normal plasma cells were isolated from bone marrow of healthy donors using CD138-coated magnetic beads (Miltenyi Biotec, Germany) as normal control. NCI-H929, RPMI8226, U226 and OPM2 cells were cultured in 90% RPMI-1640 medium (Gibco, USA) (containing 1.5 g/L NaHCO3, 2.5 g/L glucose and 0.11 g/L sodium pyruvate) supplemented with 10% fetal bovine serum (FBS) (Gibco, USA); JJN3 cells were cultured in 40% DMEM medium (Gibco, USA) and 40% IMEM medium (Gibco, USA) supplemented with 20% FBS (Gibco, USA). All cells were incubated at 37 °C under 95% air and 5% CO2 condition.

Human MM cell lines, KMS-28BM, U266, RPMI-8226 and NCI-H929, were purchased from the American Type Culture Collection. All cells were cultured in RPMI-1640 medium (Gibco; Thermo Fisher Scientific, Inc.) supplemented with 10% (KMS-28BM, RPMI-8226 and NCI-H929) or 15% fetal bovine serum (U266) (Gibco; Thermo Fisher Scientific, Inc.) and 1% penicillin and streptomycin at 37°C in a humidified incubator containing 5% CO2. The plasma cells were isolated from bone marrow mononuclear cells, which were derived from the bone marrow samples of patients with MM and healthy bone marrow donors. Briefly, after collection, the bone marrow samples were processed with gradient density centrifugation (865 × g at 37°C for 20 min) for separating the bone marrow mononuclear cells; subsequently, the separated bone marrow mononuclear cells were purified using CD138-coated magnetic beads (Miltenyi Biotec GmbH) to obtain plasma cells (22 (link),23 (link)). The plasma cells were then stored in liquid nitrogen for further analysis. After incubation at 37°C for 24 h, SIRT2 expression in MM cell lines and normal plasma cells (from healthy bone marrow donors that were used as the control group) was determined by RT-qPCR and western blot analysis.

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.
