To test the effect of drug treatment on protein and phosphoprotein levels, cell lines were dosed with drugs focused on the PI3K pathway including buparlisib (BKM-120, Selleck Chemicals), alpelisib (BYL-719, Selleck chemicals), IPI-549 (Selleck Chemicals), sirolimus (rapamycin, Selleck Chemicals), and ipatasertib (GDC-0068, Selleck Chemicals). To determine dosing for imaging-based experiments, all drugs were screened against each cell line to determine IC50 values via conventional cell viability assay (MTT). Treatments were administered at 80% of the IC50 dosing overnight prior to fixation for cell line treatments (Fig. 5b, Supplementary Fig. 10).

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.
