Ba/F3 cells were purchased from DSMZ and maintained in 90% RPMI (Gibco), 10% HI-FBS (Gibco), 1% penicillin/streptomycin (Gibco), and 10ng/ml IL-3 (Fisher), and incubated at 37°C with 5% CO2. Ba/F3 cells were passaged at or below 1.0E6 cells/ml in order to avoid acquired IL-3 resistance, and regularly checked for IL-3 addiction by performing 3x PBS (Gibco) washes and outgrowth in the absence of IL-3 to confirm cell death in the parental, empty cell line.
Plat-E cells stably expressing retroviral envelope and packaging plasmids were originally gifted by Dr. Wendell Lim. Plat-E cells were maintained in 90% DMEM+HEPES (Gibco), 10% HI-FBS (Gibco), 1% penicillin/streptomycin (Gibco), 10ug/ml blasticidin, 1ug/ml puromycin, and incubated at 37°C with 5% CO2. Plat-E cells were maintained under blasticidin and puromycin antibiotic pressure unless being transfected.
HEK293 cells were maintained in DMEM (Gibco) supplemented with 10% FBS (Gibco) and 1% penicillin/streptomycin (Gibco) at 37°C in 5% CO2.

Check if the same lab product or an alternative is used in the 5 most similar protocols
K562 cells with a doxycycline-inducible CRISPRi were a gift of the Lander lab and identical to those used in previous studies17 (link). Cells were grown in RPMI 1640 GluteMAX (Gibco) with 10% heat inactivated FBS (HI-FBS, Gibco). Cells were induced with CRISPRi for 24 h with a final concentration of 1 μg/ml doxycycline (VWR). In tests of guides for FADS, GATA1, and MYC, doxed and undoxed distributions were highly correlated (Spearman ρ = 0.91, 0.80, and 0.86, respectively). Non lenti-library infected cells were periodically sorted on BFP signal when BFP/CRISPRi expression dropped below 80%. Jurkat and GM12878 cells were grown in RPMI 1640 GluteMAX with 15% HI-FBS, 293T cells were grown in DMEM (Gibco) with 10% HI-FBS, SK-N-SH cells were grown in EMEM (ATCC) with 10% HI-FBS, and TF1 cells were grown in RPMI 1640 GluteMAX (Gibco) with 10% heat-inactivated FBS, 2 mM L-Glutamine and 2 ng/ml recombinant human Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) (Peprotech). All cells were grown at 37 °C and 5% CO2. Cells were not synchronized prior to performing HCR-FlowFISH.

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.
