Penumbra was dissected from brain ischemia and then homogenized in the RIPA lysis buffer (Beyotime, Nantong, China) containing a whole proteinase inhibitor cocktail. A BCA protein assay kit (Beyotime) was used to determine the protein concentration. The extracted proteins were separated by 10% sodium dodecyl sulfate–polyacrylamide gel electrophoresis and electrically transferred to polyvinylidene difluoride membranes. Then, the membranes were blocked with 5% nonfat milk for 1 h at room temperature. The following primary antibodies were used: mouse anti-NLRP3 (1:1,000; Adipogen, San Diego, California, USA), rabbit anti-pro–caspase-1 (1:1,000; Santa Cruz, California, USA), rabbit anti-cleaved–caspase-1 (1:3,000; Adipogen, San Diego, California, USA), goat anti–Iba-1 (1:2,000; Abcam, Cambridge, London, UK), and mouse anti-GAPDH (1:1,000; Cell Signaling Technology, Boston, Massachusetts, USA).

Western blot was performed as previously reported (Dong et al., 2020 (link)). Lumbar enlargement segments of the spinal cord were dissected and the dorsal and ventral horns were carefully separated under a stereo microscope. Tissues were homogenized by sonication in RIPA buffer containing protease inhibitors. Debris was cleared by centrifugation at 12,000 g for 10 min at 4°C. Samples were resolved on SDS-PAGE and transferred to nitrocellulose membranes, which were incubated in PBS (phosphate buffered saline) containing 0.1% Tween-20 and 5% BSA for 1 hr at room temperature (RT) before overnight primary antibody incubation at 4°C. After wash, membranes were incubated with HRP-conjugated secondary antibody in PBS for 1 hr at RT. After incubating with enhanced chemiluminescence, immunoreactive bands were visualized by LI-COR Odyssey infrared imaging system. Intensity of immunoreactive bands were quantitated with ImageJ (NIH), with β-actin or GAPDH as loading control. The following primary antibodies were used: rabbit anti-ErbB4 (#0618, 1:2,000, generously provided by Dr. Cary Lai) (Zhu et al., 1995 (link)), rabbit anti-p-ErbB4 (#4757, 1:200, Cell Signaling Technology), mouse anti-β-actin (#3700, 1:5,000, Cell Signaling Technology), and mouse anti-GAPDH (#97166 1:5,000, Cell Signaling Technology).

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.
