Check if the same lab product or an alternative is used in the 5 most similar protocols
A2780 cells and ES-2 cells were maintained in MCDB105 and M199 (1:1) (Sigma, USA) containing 5% FBS (Sigma), OV90 cells were maintained in MCDB105 and M199 (1:1) with 15% FBS. OVCA420* cells were cultured in DMEM (Sigma and Caisson Labs, USA) supplemented with 10% FBS. All the media were supplemented with 100 units/MI penicillin and 100 µg/mL streptomycin. All cell lines were subjected to cell line identity confirmation. A2780-Cas9 stable cells were established by lentiviral transducing A2780 cells with pLenti-cas9 followed by selection with 400 µg/mL blasticidin for 2 weeks. ES-2, OVCA420* and OV90 cells were gifts from Dr. Viji Shridhar (Mayo Clinic). A2780 cell was from Dr. Andrew Godwin (The University of Kansas Medical Center). All experiments performed on cells that were passaged <20 times. Mycoplasma testing was performed during the studies, and cell cultures were free of mycoplasma. Cell line identification was performed at the end of experiments. OV90 showed 100% STR profiles matching to corresponding cell lines reported in ATCC or ExPASy. STR profiles for ES-2 and A2780 were performed in 2014 as a supplement to our recent publication60 (link). STR profiles for OVCA420* does not match with any reported cell lines in ATCC, ExPASy, DSMZ, or CLIMA, and therefore we placed an asterisk to differentiate it from the original cell line.

The human ovarian cancer PEO1 and PEO4 cells (Sigma) were cultured in RPMI-1640 with 10% Fetal Bovine Serum (FBS). IGROV1 cells (a generous gift form Wei Zheng) was cultured in DMEM with 10% FBS. OV90 (ATCC) was cultured in the growth medium containing 1:1 MCDB 105 (Sigma) and M199 (Sigma) supplemented with 10% FBS. All the cells were cultured at 37 °C in a humidified incubator containing 5% CO2.
Cisplatin resistant cell lines IGROV1 CR and OV90 CR were established by following the previous report40 (link). Briefly, IGROV1 and OV90 cells were treated with cisplatin for six cycles (4 hours of cisplatin treatment, followed by release to cisplatin free medium for three weeks). In the next cycle, cisplatin treatment was repeated with an increased concentration of cisplatin. After five months of treatment (6 cycles), cisplatin resistant cell lines IGROV1 CR and OV90 CR were obtained. Only early-passage (<10 passages) resistant cell lines were used for the study.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The EFO-27 cell line is commercially available and was originally derived from a solid metastasis of a mucinous papillary ovarian carcinoma68 (link). The GTFR230 mucinous ovarian cancer cell line was created in house and derived from a stage IC low grade primary mucinous ovarian cancer collected as part of the Gynecological Tissue and Fluid Repository (GTFR) at the University of Southern California (USC). We routinely profile cell lines using STR profiling (using the Powerplex 16 panel) at the University of Arizona Genetics Core facility and screen for mycoplasma using a mycoplasma-specific PCR. A piece of the tissue removed during surgery was transferred to the cell culture laboratory, minced into small pieces (1–2 mm diameter) and placed into NOSE-CM69 (link) which consists of Medium 199 mixed in a 1:1 ratio with MCDB105 (Sigma), 15% fetal bovine serum (FBS, Hyclone), 10 ng/ml epidermal growth factor (EGF), 34 μg/ml bovine pituitary extract (Life Technologies), 500ng/ml hydrocortisone and 5 μg/ml insulin (Sigma). Cells were confirmed to be epithelial in origin by staining for cytokeratin.

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.
