Lysates were prepared and electrophoresed on gels as described previously (32 ). Membranes were probed with primary antibodies following each of the supplier’s recommendations: AKT (#4685), pAKT (S473) (#4060), ATG5 (#2630), caspase-3 (#9662), Cleaved PARP (D214) (#9541), p-eIF2α (S51) (#3398), ERK1/2 (#9102), pERK1/2 (T202/Y204) (#9101), GCN2 (#3302), LC3B (#2775), PRAS40 (#2610), pPRAS40 (T246) (#2997), and p62 (#5114) from Cell Signaling Technology (Danvers, MA), and p21 (sc-756), p27 (sc-528), Cyclin D1 (sc-718), α enolase (sc-7455), VDAC1 (sc-8828), and ERK2 (sc-1647) from Santa Cruz Biotechnology (Dallas, TX, USA). The P5CS primary antibody, ALDH18A1 (NBP1-83324), was purchased from Novus Biologicals (Littleton, CO, USA) and pGCN2 (T899) (ab75836) from Abcam. eIF2α and eIF2Bε antibodies were kind gifts from Dr. Scot Kimball. Secondary antibodies goat anti-rabbit IgG-HRP (sc-2004), goat anti-mouse IgG-HRP (sc-2005), and donkey anti-goat IgG-HRP (sc-2020) were purchased from Santa Cruz Biotechnology. The immunoblots were developed using ECL Western Blotting Substrate (Thermo Scientific) or Supersignal West Femto Chemiluminescent Substrate (Thermo Scientific).

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.
