Check if the same lab product or an alternative is used in the 5 most similar protocols
HK2 cell lines, which express HA-PRCC-TFE3, HA-SFPQ-TFE3, or HA-NONO-TFE3 doxycycline-dependently, were established by two sequential lentiviral transductions using the full-length rtTA3(Tet-on) gene (Takara) and the HA-PRCC-TFE3, HA-SFPQ-TFE3, or HA-NONO-TFE3 genes under control of the TRE-tight promoter. Cells were cultured in Advanced DMEM/F-12 with 1.5% Tetracycline-Free Fetal Bovine Serum (Takara) and selection antibiotics, 2 µg/mL Blasticidin S, and 0.8 µg/mL Puromycin. For gene expression profiling, HK2 lines were cultured with or without 200 ng/mL doxycycline. Total RNA was isolated from cells using TRIzol reagent (Invitrogen). cDNA preparation and hybridization were performed according to the manufacturer's protocol (Affymetrix). Affymetrix GeneChip Human Genome U133 Plus 2.0 arrays were applied. RMA-based data normalization and subsequent data analysis, including PCA and ANOVA, were performed with Partek Genomics Suite 6.6.

HeLa and DLD-1 Cell Culture and Transfection

Check if the same lab product or an alternative is used in the 5 most similar protocols
HeLa and DLD-1 cells were maintained at 37°C in a 5% CO2 atmosphere in DMEM (Thermo Fischer Scientific, Waltham, MA) supplemented with 10% tetracycline-free fetal bovine serum (Clontech, Mountain View, CA), 100 U/ml penicillin, 100 U/ml streptomycin, and 2 mM l-glutamine. For immunofluorescence, cells were seeded on 12-mm poly-l-lysine–coated coverslips in 12-well plates 24 h before transfection with siRNAs. For live-cell imaging experiments, cells were seeded in a 35-mm glass-bottom dish coated with poly-d-lysine (MatTek, Ashland, MA). Cells were transfected with siRNAs targeting Spindly and the CENP-E 3′ UTR as described previously (Gassmann et al., 2010 (link); Kim et al., 2010 (link)). For immunofluorescence of HeLa Flp-In T-Rex cells, transgene expression was induced with 0.2 μg/ml tetracycline 24 h posttransfection, and cells were fixed 20–24 h later. For live-cell imaging of HeLa Flp-In T-Rex cells and for the immunoblot shown in Figure 5A, transgene expression was induced 22 h after transfection, and time-lapse imaging experiments were started 8 h later.

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.
