LNCaP (ATCC, Manassas, VA, CRL-1740), DU 145 cells (ATCC, HTB-81), NIH3T3 (ATCC, CRL-1658), hTERT-HPNE (ATCC, CRL-4023), PANC-1 (ATCC, CRL-1469), and 293T (ATCC, CRL-3216) were cultured as recommended by ATCC. Cell lines were authenticated by IDEXX Laboratories in August 2014. A patient-derived fibroblast cell line [36 (link)], which was cultured in RPMI 1640 supplemented with 10% fetal bovine serum, was also tested. Compounds were tested in triplicate. Cells were plated at 4 × 103 cells per well in 96-well plates with 100 μL per well RPMI or DMEM containing 10% v/v fetal bovine serum and 100 μg/mL each of penicillin and streptomycin. Each well was immediately treated during cell plating with one compound at final concentrations of 200 to 0.390625 μM at twofold serial dilutions. Each experiment also included a condition with 0.5% v/v DMSO but no compound. Cell growth was measured using PrestoBlue Cell Viability Reagent (Life Technologies, Carlsbad, CA) following 72 hours of incubation at 37°C in 5% CO2. Eleven microliters of the reagent was added to cells in each well and then incubated 60 minutes at 37°C in 5% CO2. Emission at 612 nm (excitation: 525 nm) was recorded to measure resazurin production. Emission data were normalized so that cells tested against DMSO only (no compound) represent 100% growth.

All cell lines were maintained in a humidified incubator at 37 °C in 5% CO2. PANC-1, hTert HPNE, Mia PaCa-2, HPAF-II, and AsPC-1 cells were purchased from ATCC and used experimentally within five passages. All cell lines were maintained according to ATCC recommendations, and ATCC authenticated the cell lines by short tandem repeat (STR) DNA profiling. The cells were verified to be mycoplasma-free by using the MycoProbe Mycoplasma Detection kit (R&D Systems, Minneapolis, MN). Cas9 stable cell lines were made by virally transducing cells with LentiCAS9-Blast (Addgene, Cambridge, MA; cat. # 52962) [15 (link)] and selecting with 8 μg/mL of blasticidin for 5 days. Expression was verified by Western blot analysis (Additional file 1b).

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.
