BT20, BT474, HCC1428, HCC38, LY2, MCF7, MDAMB231, MDAMB453, T47D, SUM52PE, and
ZR75B cell lines were obtained from the American Type Culture Collection (ATCC).
Cell lines used for proteomic profiling and molecular analyses were
authenticated by STR analysis. Lines were grown according to published
protocols50 except for
SKBR3 which was cultured using RPMI media supplemented with 10% fetal
bovine serum (FBS) and 1% pen/strep. All cell lines tested negative for
mycoplasma contamination. Drugs used for cell culture experiments in this study
were purchased from Selleck Chemicals (GDC-0941, MK2206, PD0325901, Lapatinib,
MLN8237, and LEE011) and LC Laboratories (RAD001).

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.
