The Hap1 cell line (8 (link)) was kindly provided by Dr. Thijn Brummelkamp, Netherlands Cancer Institute. The 293FT cell line used to generate high-titer lentiviruses was obtained from ThermoFisher Scientific; the A549, PC3, MDA-MB-361, HCC-1954 and NCI-H1650 cell lines were purchased from ATCC, where they were validated by STR profiling, and used at passage numbers <5. The KOPN8 cell line was a generous gift from Professor Michael Cleary, Stanford University. The Phoenix-Ampho cell line used for retrovirus production was purchased from Allele Biotechnology (San Diego, CA).
Null alleles for genes were constructed using the CRISPR/Cas9 system. For Hap1 cells the oligos encoding the guide RNAs were cloned into pSpCas9(BB)-2A-GFP (PX458, Addgene Plasmid #48138 from Dr. Feng Zhang) (9 (link)). Single cells were sorted using flow cytometry, expanded and clones bearing null alleles were identified by Sanger sequencing and immunoblotting. For gene disruption in cancer cell lines, the gRNAs validated in the Hap1 cells were introduced into LentiCRISPR v2 (Addgene Plasmid #52961 from Dr. Feng Zhang) (10 (link)) for lentiviral-mediated delivery. The oligo sequences for guide RNAs are provided in the supplementary methods.

Check if the same lab product or an alternative is used in the 5 most similar protocols
To investigate the therapeutic effect of Sal-B on NSCLC metastasis, two NSCLC cell lines (NCI-H2030 and NCI-H1650; ATCC, USA) were selected. All cells were grown in DMEM (Hyclone, USA) plus 10% fetal bovine serum (FBS; Hyclone) at 37°C in a humidified environment of 5% CO2. Sal B (purity ≥98%; Hongqiao Pharmaceutical Technology Research Institute Co., Ltd., Nanjing, China) was dissolved in absolute ethanol to 50 mM and stored at −80°C. Moreover, TEPP-46 was acquired from MedChemExpress Company (USA). NSCLC cell lines were treated with 10 μM TEPP-46 for selectively activating pyruvate kinase M2 (PKM2).

NSCLC cell lines were obtained from the H. Lee Moffitt Lung Cancer Center of Excellence Cell Line Core and maintained in RPMI medium supplemented with 10% heat-inactivated fetal bovine serum and 1% Streptomycin/Penicillin. The cell lines used were the following: NCI-H1666 (ATCC CRL-5885, human adenocarcinoma), NCI-H520 (ATCC HTB-182, human, squamous cell carcinoma), NCI-H1650 (ATCC CRL-5883, human adenocarcinoma), NCI-1975 (ATCC CRL-5908, human adenocarcinoma), NCI-H596 (ATCC HTB-178, human adenosquamous carcinoma), and NCI-H60 (ATCC CRL-5821, human small cell lung carcinoma). Cell lines were cultured in 100 mm plates and kept in a humidified water-jacketed incubator at 37°C and 5% CO2 and passaged every 5–7 days to maintain a confluence of approximately 80%. Cell lines tested negative for mycoplasma contamination and were authenticated by short tandem repeat (STR) analysis of loci TH01, TPOX, vWA, CSF1PO, D16S539, D7S820, D13S317 and D5S818. Genotypes of both cell lines were based on the Cell Line Encyclopedia as previously described [20 (link)].

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.
