OP9 (RCB1124), TSt-4 (RCB2116), NIH 3T3 (RCB2767), NALM6 (RCB1933), and K562 (RCB0027) cells were purchased from RIKEN Bio Resource Center (Tsukuba, Ibaraki, Japan) within 10 years. OP9, TSt-4, and NIH 3T3 cells were cultured in minimum essential medium-alpha modification (αMEM; Thermo Fisher Scientific) supplemented with 20% FBS (Sigma-Aldrich) and 1% penicillin-streptomycin (Nacalai Tesque). NALM6 and K562 cells were cultured in RPMI1640 (Nacalai Tesque) supplemented with 10% FBS and 1% penicillin–streptomycin as described previously (13 (link)). OP9-hDLL1 and K562-hCD19 cells have been described previously (11, 26 (link)). HEK293T and Expi293F cells were purchased from (ATCC) and Thermo Fisher Scientific within 10 years, respectively. These cells were cultured in DMEM (Nacalai Tesque) supplemented with 10% FBS and 1% penicillin–streptomycin as described previously (1 (link)). All cell lines were regularly tested for Mycoplasma contamination using BioMycox Mycoplasma PCR Detection Kit (CellSafe) and were frozen down at early passages (<7) and used in the experiments within five passages after thawing. These cells were not further authenticated by our laboratory; however, routine confirmation of in vitro growth properties, morphology, and transfection efficiency (HEK293T and Expi293F) provided evidence of correct cell identity.

Each cell was grown in 10 cm polystyrene tissue culture dishes at 37°C in a 5% CO2 incubator. All the T cells were prepared from the spleen of OT-I and C57BL/6 mice. Splenocyte suspensions were prepared by pushing the spleens through a cell strainer (Corning). After treatment with ACK lysis buffer for 5 min at room temperature (RT) to remove the red blood cells, the splenocytes were washed twice and re-suspended in R-10 complete medium.

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.
