Consecutive sections (4-μm) of tissue microarray samples were mounted on the APES-coated slides. After de-paraffinization, rehydration and antigen retrieval using an autoclave-oven-technique, sections were incubated with anti-PRR11 (HPA023923, SIGMA-ALDRICH), UCHL1 (HPA005993, SIGMA-ALDRICH), SNAT1 (ab59721, abcam®), and EGR1 (ab54966, abcam®) at 4°C overnight. A two-step EnVisionTM KIT (DAKO, USA) was used to visualize positive staining. Lung cancers known to be positive for these proteins were used as positive controls. Replacement of the primary antibody by PBS served as a negative control.

The following antibodies were used in this study: SLC1A5 (ab84903, Abcam), glutaminase 2 (GLS2; ab113509, Abcam), GOT1 (PA5-24634, Thermo), SLC38A1 (ab59721, Abcam), Flag (F3165, clone M2; SigmaAldrich), Actin (sc-8432, Santa Cruz). HRP-labeled secondary antibody conjugates were purchased from Molecular Probes (Thermo). Erastin (#E7781), RSL3 (#S8155), and ferrostatin-1 (#S7243) were obtained from Selleck Chemicals (Houston, TX, USA). Necrosulfonamide (ab143839) and Z-VAD-FMK (ab120382) were obtained from Abcam. Compound 968 (352010), GPNA (G1135), and amino-oxyacetate (AOA; C13408) were obtained from Sigma.

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.
