Check if the same lab product or an alternative is used in the 5 most similar protocols
Human ESCC cell lines including EC9706, EC109, KYSE410, KYSE150, and KYSE450 were all available from the ATCC (Manassas, VA, USA) for cell culture with 5% CO2 at 37 °C. RPMI‐1640 medium (Gibco, Carlsbad, CA, USA) was acquired commercially, with 1% Pen/Strep mixture and 10% FBS as supplements. Medium was changed every 3 days. After cells had reached about 80% confluence at the 3rd passage, CD133+ cancer cells were obtained by treating with MACS CD133 kit (Miltenyi Biotec, Teterow, Germany). ESCC cells without treatment were termed CD133 cancer cells as control. About 2 mg·mL−1 of actinomycin D was procured from Sigma‐Aldrich (St. Louis, MO, USA) to treat cells.

Analytical Validation of PNA-Based qPCR for KRAS Mutations

Check if the same lab product or an alternative is used in the 5 most similar protocols
The polypeptide nucleic acid (PNA) based qPCR assay that was used for the detection of KRAS mutations and its analytical validity, sensitivity and specificity have been previously described [20] (link), [21] . The following tumor cell lines, positive for each KRAS point mutation, were obtained from the American Type Culture Collection (ATCC, Manassas, VA, USA) and used in control experiments: LS174T (Human colon adenocarcinoma): c.35G > A (p.G12D); HCT116 (Human colon adenocarcinoma): c.38G > A (p.G13D); HUP-T3 (Human pancreatic adenocarcinoma): c.34G > C (p.G12R); KYSE410 (Human esophageal squamous cell carcinoma): c.34G > T (p.G12C); A549 (Human alveolar adenocarcinoma: c.34G > A (p.G12S); SW403 (Human colon adenocarcinoma): c.35G > T (p.G12 V) and RPMI8226 (Human myeloma): c.35G > C (p.G12A)] or wild type for KRAS (HCC827, Human lung adenocarcinoma) at 1:1 and 1:100 concentrations. [20] (link), [21] . In each run, positive and negative controls were included as well as non-template controls. All samples were run in triplicates and a sample was considered as positive if there was at least one positive signal, consistent with previously published studies [22] (link).

The Human gastric cancer cell lines SNU16, HGC27, MKN45, NCI-N87, KATO III, MKN7, SNU216, MKN74, human esophageal cancer cell lines KYSE-410, OE19 and prostate cell line PC3, were purchased from the American Type Culture Collection (ATCC, Rockville, MD, USA). All cells except for PC3 were cultured in RPMI 1640 (GIBCO) supplemented with 10% FBS (Invitrogen) and 1% penicillin-streptomycin (Invitrogen). PC3 cells were cultured in DMEM (GIBCO) supplemented with 10% FBS and 1% penicillin-streptomycin. All cells were maintained in a humidified atmosphere of 95% air and 5% CO2 at 37 °C. Cells were tested negative for mycoplasma contamination.

Jung (Institute of Pathology, Ludwig-Maximilian-University, Munich, Germany). All cell lines were cultured in flasks according to supplier's recommendations, before subsequent harvesting using 0.25% trypsin and 5 mmol/L EDTA (GIBCO-BRL). Authentication was done by determining the KRAS mutational status of each cell line by Sanger sequencing. All cell lines except SW403 were heterozygous for KRAS mutations and revealed the expected genotype.

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.
