Anti il 18

Lysis and protein extraction of spinal cord tissues or astrocytes was performed using the RIPA lysate buffer (P0013; Beyotime). The concentration of the extracted protein was determined by the BCA Protein Assay Kit (P0011; Beyotime). The protein (20–40 µg per lane) was separated on 8–15% SDS-PAGE gel and transferred to polyvinylidene fluoride membrane (IPVH00010; Millipore, Billerica, MA, USA). After blocking with 5% (m/v) skim milk for 1 h at room temperature, the membrane was incubated at 4 °C overnight with primary antibodies in skim milk at a dilution of 1:1000. These primary antibodies were as follows: anti-HSPA8 (A14001; Abclonal), anti-NLRP3 (A5652; Abclonal), anti-ASC (A1170; Abclonal), anti-caspase-1 (A0964; Abclonal), anti-NF-κB P65 (AF5006; Affinity, Cincinnati, OH, USA), anti-phosphorylated NF-κB P65 (p-NF-κB P65) (AF2006; Affinity), anti-IL-1β (A16288; Abclonal), anti-IL-18 (A16737; Abclonal), and anti-β-actin (sc-47778; Santa Cruz). After washing with Tris-buffered saline-Tween 20 (TBST) buffer, the membranes were incubated with horseradish peroxidase (HRP)-conjugated goat anti-rabbit (1:3000 dilution; A0208; Beyotime) or mouse (1:3000 dilution; A0216; Beyotime) secondary antibody at 37 °C for 40 min. The membranes were visualized using a chemiluminescence kit (Shanghai 7sea biotech Co. Ltd.) and analyzed using Gel-Pro-Analyzer 4.0 (Media Cybernetics, Inc.).

Total protein was extracted from cell lysates. Western blot analysis was performed using standard methods [13 (link)]. Primary antibodies: anti-NLRP3 (A12694; ABclonal, China);anti-IL17A (A0688; ABclonal, China);anti-IL17-RA (A10052; ABclonal, China);anti-IL1β(A12688; ABclonal, China); anti-IL18(A1115; ABclonal, China); anti-oxidative phosphorylation (OxPhos) complexes (I-NDUFB8, A19732; II-SDHB, A1809; III-UQCRC2, A4366; IV-MTCO2, A11522 and ATP5J, A3751; ABclonal, China).
