Protein Expression Analysis by Western Blot

Total proteins were prepared with RIPA lysis buffer (Beyotime, China). Concentrations of protein were examined by BCA assay. Equal amounts of protein were separated by 10% SDS-PAGE and electrotransferred onto polyvinylidene difluoride membranes (Bio-Rad, United States). After being blocked using 5% non-fat milk for 1 h at room temperature, the primary rabbit anti-human antibodies against S100A10 (ab76472, Abcam) and GAPDH (ab9485, Abcam) were supplemented overnight at 4°C. Then the members were washed with tris-buffered saline Tween 20 for three times and probed with horse radish peroxidase-conjugated secondary antibodies (ab205718, Abcam) for 1 h at 37°C. The bands were visualized using a ChemicDocXRS system (Bio-Rad, United States).

Protein Extraction and Western Blotting

The cells were lysed with RIPA lysate (containing 1% PMSF), and the supernatant was collected after the high-speed centrifugation. Subsequently, the Bradford method was used for protein quantification. Then the sample was heated in a water bath at 100°C for 10 min. SDS-PAGE was used to separate the proteins and then the proteins were transferred onto polyvinylidene fluoride (PVDF) membranes. After that, the membrane was blocked at room temperature with 5% skimmed milk for 1 h, followed by being added with anti-Anti-APE1 antibody (ab76472) (1:1000; Abcam, Cambridge, UK) and Anti-β-actin antibody (ab115777) (1:1000; Abcam, Cambridge, UK) for incubation overnight at 4°C and then rinsed with TBST solution. Subsequently, the membrane was incubated with secondary antibodies (Beyotime, Shanghai, China) for 1 h at room temperature before being washed 3 times. At last, color rendering was performed using hypersensitive ECL (Biossci Biotechnology Co, Ltd., Wuhan, China).

Western blot analysis was performed as previously reported (Jiang et al., 2016 (link); Bier et al., 2018 (link)). Briefly, cell lysates were solubilized with RIPA buffer supplemented with PhosSTOP and Complete Phosphatase/Protease Inhibitor Cocktails (Roche Diagnostics) and protein content was analyzed using a standard BCA assay. Protein extract (20–30 μg per sample) were loaded on sodium dodecyl sulfate-polyacrylamide electrophoresis gels and transferred to PVDF membranes that were probed with the specific antibodies as detailed. Bound antibodies were visualized with an enhanced chemiluminescence detection kit (Amersham Pharma-Biotech). Equal loading was verified using an anti actin antibody. The following primary antibodies were used: Anti-TrkB (Cat# sc-136990, 1:500), anti-p75 (Cat# sc-13577, 1:1,000), and anti-EAAT2 antibodies (Cat# sc-365634, 1:500) (Santa Cruz Biotechnology). Anti-cleaved PARP1 (AB3820, 1:1,000), Anti-cleaved caspase 3 (ab2303, 1:500), anti-C3 (ab97462, 1:500) anti-S100A10 (ab76472, 1:500) and exosome panel antibody (ab275018) (Abcam, Cambridge, MA United States). Anti-mouse and anti-rabbit HRP secondary antibodies (1:10,000, Pierce).

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.
