Ovarian Cancer Cell Culturing and Co-Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
The majority of the experiments described here used OVCAR-3 cells (ATCC, Manassas, VA), a human epithelial ovarian cancer cell line. OVCAR-3 cells were subcultured under standard cell culture conditions in RPMI medium supplemented with 20% fetal bovine serum, 0.01 mg/mL bovine insulin, and 1% penicillin–streptomycin. For experimentation, near confluent cells from stock T-75 flasks were detached with 0.25% trypsin–EDTA and subcultured onto 18 mm round glass coverslips at a 1:5 split ratio and grown for 5 days in standard culture conditions prior to experimentation. OVCAR-3 cells used here were passage number 35–50.
For co-culture experiments, Hs-27 cells (ATCC), a human fibroblast cell line, were seeded at equal densities and grown with OVCAR-3 cells on glass coverslips under similar conditions. Dulbecco’s Modified Eagle’s Medium with 10% fetal bovine serum was mixed at a 1:1 ratio with the RPMI medium described above for co-culturing Hs-27 and OVCAR-3 cells.

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.
