The human DLBCL-derived cell lines SU-DHL-4, SU-DHL-6, OCI-LY19, U-2932, and Ri-1 were obtained from the German Collection of Microorganism and Cell Cultures, Department of Human and Animal Cell Cultures; DB, SU-DHL-8, and the BL cell lines RAJI, Ramos, and Daudi were obtained from ATCC. The DLBCL-derived cell lines (HBL-1 and TMD8) were provided by R. E. Davis, MD Anderson Cancer Center, Houston. Cell lines were cultured in RPMI medium 1640 supplemented with 10 or 20% heat-inactivated FBS (Gibco BRL), 1% l-glutamine, and penicillin–streptomycin in a humid environment of 5% CO2 at 37 °C.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human DLBCL cell lines OCI-Ly01, VAL, OCI-Ly10, SUDHL-8, Farage, and SUDHL-4 cells were purchased from ATCC (Shanghai, China) and cultured in RPMI-1640 medium (Hyclone, Utah, USA) supplemented with 10% fetal bovine serum (FBS) (Ausgenex, Australia), 100 U/mL penicillin, 100 U/mL streptomycin, and 2 mM L-glutamine. Human embryonic kidney 293T cells were maintained in Dulbecco modified Eagle media (DMEM; Hyclone) with 10% FBS. Cells were cultured at 37°C in a 5% CO2 humidified incubator.
Lentiviral plasmids containing optimized CD300A short hairpin (shRNA) or scramble sequences were produced using 293T cells, and were used to infect DLBCL cells as described [4 (link), 33 (link)]. The sequences for CD300A shRNAs used in the present study included shRNA-1 (5′-GATGTTTCAGAAATGGATCAA-3′), shRNA-2 (5′-CCCAGGGAAGAACTTCACTAT-3′), and a scramble shRNA (5′-CCTAAGGTTAAGTCGCCCTCG-3′).
The surface expression of CD300A in lymphoma cells was determined using a phycoerythrin (PE)-conjugated antibody against human CD300A (clone E59.126, Beckman Coulter, Marseille, France). After staining for 30 min on ice, cells were resuspended in phosphate-buffered saline (PBS) and analyzed using a FACS Calibur instrument (Becton Dickinson, CA, USA). The isotypic antibody (clone 679.1Mc7, Beckman Coulter) was used as control.

Forty-five cases of lymphoma tissues were obtained from DLBCL patients who were diagnosed and had undergone surgical resection at Xianning Central Hospital (Hubei, China) between August 2010 to March 2016. Additionally, 23 cases of reactive lymphoid hyperplasia tissues were collected in the same period, and were selected as negative controls. No local or systemic therapy was conducted in these participators before operation. Primary CD19+ cells were obtained from the serum of healthy volunteers through positive selection with CD19+ MicroBeads antibody (Miltenyi Biotec, Auburn, CA, USA). Written informed consent was obtained from all participants, and the study was approved by Institutional Review Board of Xianning Central Hospital.
Three DLBCL cell lines (SU-DHL-8, OCI-LY1, and SU-DHL-10) were purchased from American Type Culture Collection (ATCC, Manassas, VA, USA), and were cultured in RPMI-1640 medium (Thermo Fisher Scientific, Tempe, AZ, USA) plus 10% fetal bovine serum (FBS, Thermo Fisher Scientific), 2 mmol/L L-glutamine (Thermo Fisher Scientific) and 100 units/mL penicillin/streptomycin (Thermo Fisher Scientific), at 37℃ in 5% CO2.

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.
