After two washings with cold PBS, cells were lysed in ice-cold lysis buffer (SDS 1% EDTA 10 mM; Tris-HCl pH8,1 50 mM; protease inhibitors, Na3VO4 1 mM, NaF 100 × ) and extracts were sonicated. Protein extracts were separated by SDS-PAGE, transferred onto a PVDF membrane (Millipore, Billerica, MA, USA) and revealed with a chemiluminescence kit (Millipore). Presented Western-Blot are representative of three independent experiments. Following antibodies were used: actin (MAB1501R, Millipore), β-tubulin (T0198, Sigma), BAX (A3533, Dako), BCL-xL (1018-1, Epitomics), cytochrome c (BD-Pharmingen San Diego, CA, USA), MCL-1 (sc-819, Santa Cruz Biotechnologies, Santa Cruz, CA, USA), NOXA (ALX-804-408, Enzo Life Science, New York, NY, USA), PUMA (12450, Cell Signalling), p21 (2947, Cell Signalling), p53 (#554294, BD-Pharmigen).

A polyclonal antibody that recognizes both ubiquilin-1 and ubiquilin-4 was raised by immunizing rabbits with recombinant full-length ubiquilin-4 proteins. For immunohistochemistry, monoclonal antibodies against Rpn13 were raised by immunizing rats with recombinant full-length Rpn13 proteins. The antibodies for Tubulin (sc-5286; Santa Cruz Biotechnology), Ki-67 (RM-9106; Thermo Scientific), Nrf1 (sc-13031; Santa Cruz Biotechnology), β-catenin (610153; BD biosciences), p62 (PM045; MBL), Actin (MAB1501R; Millipore), and GAPDH (MCA4739; AbD Serotec) were purchased.

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.
