All human T-ALL cell lines (KOPT-K1, DND41, JURKAT, SUP-T13, HPB-ALL, MOLT-4, MOLT-16, RPMI-8402, TALL-1, and LOUCY) were obtained from ATCC (Manassas, VA, USA) or DSMZ (Braunschweig, Germany). The creation of Ba/F3 cells transformed by TYK2-E957D was described previously.6 (link) JURKAT and KOPT-K1 cells overexpressing BCL2 were generated with the MSCV-IRES-GFP retroviral expression system. JURKAT and KOPT-K1 cells overexpressing BCLXL or MCL1 cDNA were generated with the pHAGE-CMV-IRES-ZsGreen lentiviral expression system. For additional information, see Supplementary Materials and Methods. These cells were maintained in RPMI-1640 medium (GIBCO, Waltham, MA, USA) supplemented with 10% fetal bovine serum (Sigma-Aldrich, St. Louis, MO, USA) and 1% penicillin/streptomycin (Invitrogen, Waltham, MA, USA).

Primary lymphomas tumors and the lymphoma cell lines were collected and established in our laboratory as described previously between 2004 and 2005 (24 (link)). HPB-ALL, ALL-SIL and 293T cell lines were obtained from the ATCC (Manassas, VA, USA) and cultured under recommended condition for less than six months. Mouse embryonic fibroblasts (MEFs) were prepared from wild-type C57Bl/6 embryos at day E13.5 following a standard MEF isolation protocol (25 ) and were cultured in complete DMEM. Animal experiments were approved by the University of Miami Institutional Animal Care and Use Committee. The number of the passages of the cell lines used in this study are not exceed 15. All cell lines were maintained at 37 °C in 5% CO2 and tested for mycoplasma contamination.

Human CTCL cell lines (HH, H9, MJ, Hut 78) and T-cell acute lymphoblastic leukemia (T-ALL) cell lines (HPB-ALL, PF-382, CCRF-CEM, and Jurkat) were acquired from American Type Culture Collection (ATCC) and cultured in complete media recommended by ATCC. All cell lines were passaged 3 times per week and maintained at a cell density below 106 cells/mL, and logarithmically growing cells were used for all experiments.
SGN-CD70A (h1F6239C-PBD) and ADC-IgG control (hIgG239C-PBD) were provided by Seagen Inc. (Seattle, WA).17 (link) T-cell activation/expansion kit and recombinant cytokines, human IL-2 (hIL-2) and hIL-7, were purchased from Miltenyi Biotec (Bergisch Gladbach, Germany).

Cell Line Authentication and Maintenance

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cell lines CEM, HPB-ALL, HSB2, Jurkat, MOLT4, Loucy, and PEER were obtained from either the American Type Culture Collection (ATCC; Manassas, VA, USA) or the DSMZ (German Collection of Microorganisms and Cell Culture; Braunschweig, Germany). The Jurkat-luciferase cell line has been previously described [28 (link)]. The Loucy-luciferase cell line was generously provided by Dr. Pieter Van Vlierberghe (Center for Medical Sciences, Ghent University, Ghent, Belgium). Short tandem repeat microsatellite loci analysis was used to confirm cell line identities. Cultures were confirmed Mycoplasma-free. Frozen cell line stocks were generated at the time of authentication and thawed for experiments ≤ 3 months before use. All cell lines were cultured in RPMI medium (Gibco, ThermoFisher Scientific, Waltham, MA, USA) supplemented with 10–20% fetal bovine serum (FBS) and 1% penicillin–streptomycin (complete RPMI (cRPMI)).

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.
