Docetaxel resistant cells were prepared from the parental PC3 cells. The resistant cells were generated by gradually increasing the docetaxel concentration starting from 4nM to 40nM and were maintained in standard condition incubator for 8 months at 37°C and 5% CO2. The docetaxel resistant cells were labeled as PC3-R and were maintained in RPMI-1640 media supplemented with 10% fetal bovine serum (FBS), L-glutamine, nonessential amino acid, HEPES, 2mM L-glutamine and penicillin/streptomycin antibiotic solution (Fisher Scientific, Pittsburgh, PA).

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.
