Cell extracts were lysed in 10x RIPA solution (Merck Millipore) and or mouse striatal punches were homogenized in a urea/DTT solution, both containing a cocktail of protease inhibitors (Roche pharmaceuticals), followed ultrasound sonication. Protein concentration levels were determined using Pierce™ BCA Protein Assay Kit (Thermo Scientific) for cell lysates and using NZYBradford reagent (Nzytech) for mouse samples. Sixty to eighty protein µg were resolved in SDS-polyacrylamide gels (7.5% and 12%). Followed by protein transfer to PVDF membrane (Merck Millipore) and antibody probing using the following antibodies: mouse anti-ataxin-2 (1:1000, ref. 611378, BD Biosciences); mouse anti-IC2 (polyQ chain) (1:1000, ref. MAB1574, Merck Millipore); rabbit anti-LC3B (1:1000, ref. NB100-2220, Novus); rabbit anti-SQSTM1 (1:1000, ref. 5114S, Cell Signaling); mouse anti-β-actin (1:5000, ref. A5316, Sigma Aldrich); rabbit anti-DARP-32 (1:1000, ref. AB10518, Merck Millipore). Optical densiometric analysis was carried out using Image J software (USA).

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.
