Total proteins of ischemic brain tissue in each group were extracted by RIPA buffer containing EDTA-free protease inhibitor and phosphate inhibitor (Rocher, Switzerland). After measuring the protein concentration, 30 μg of each sample was subjected to electrophoresis on 15% SDS-PAGE gel at 200 V. The protein was transferred into the PVDF membrane at 100 V in Bio-Rad TransBlot apparatus. 5% skimmed milk diluted by TBST solution was used to block PVDF membranes containing proteins for 2.5 hours at room temperature, and then, the primary antibody, rabbit anti-GADPH (1 : 1000, Abcam, ab181602), NLRP3 (1 : 1000, Abcam, ab181602), caspase 1 (1 : 1000, Abcam, ab181602), and NF-κB (1 : 1000, Abcam, ab181602), were used to incubate PVDF membranes at 4°C overnight. And then, the second antibody HRP-conjugated goat anti-rabbit (1 : 5000; EarthOx, USA) was used to incubate membranes for 2.5 hours after washing three times per 5 mins with TBST solution. Finally, after incubating with enhanced chemiluminescence, the membranes were exposed in ChemiDoc Touch Imaging System. ImageJ software was applied to the quantification analysis of protein bands.

Western blotting was performed using the Simple Western Jess system (ProteinSimple, USA), a combination of capillary electrophoresis and immunodetection techniques, following the manufacturer’s protocols (Beekman et al. 2018 (link)). The left hippocampal samples were collected and were frozen at − 80℃ at 6 h and 7 d after microwave exposure. The hippocampus was homogenized and lysed in a mixed liquid containing radio-immunoprecipitation assay (RIPA) lysis buffer and 1% protease inhibitor after all the samples were collected. The whole process was carried out at a low temperature (0–4℃). A fully automated western blotting was carried out on an array of protein samples after the protein concentration was determined with a bicinchoninic acid (BCA) protein assay kit. Proteins were detected with the following primary antibodies: PSD-95 (ab18258, Abcam), CaMKII (ab134041, Abcam), CREB (ab32515, Abcam), (ab181602, Abcam), GluN1 (MAB363, Millipore Sigma), GluN2A (MAB5216, Millipore Sigma) and GluN2B (ab93610, Abcam). Chemiluminescent signals were captured by a charge-coupled device (CCD) camera, and the resulting images were analysed by Compass software (ProteinSimple, USA) and expressed as peak intensities. For quantification, the areas under the protein peaks were normalized to GAPDH (ab181602, Abcam) and target protein loading controls.

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.
