The frozen C3–6 DRG samples of 25 rats were prepared after tissue lysis and centrifugation for SDS-polyacrylamide gel electrophoresis. The protein with SDS sample buffer was mixed with β-mercaptoethanol, separated under reducing conditions on a 5% SDS polyacrylamide gel, and finally transferred to a nitrocellulose membrane. Blocking was carried out in 3% BSA (VWR International LLC, Solon, OH, USA) solution for 30 minutes at room temperature. The membrane was incubated with rabbit anti-GABAAα2R (1:1,000, AGA-002; Alomone Labs) and rabbit anti-GAB-ABR1 (1:1,000, ab90883; Abcam). GAPDH (1:20,000; YM3029, ImmunoWay, Plano, TX, USA) was used as a standard. After overnight agitation at 4°C, the sample was then incubated with HRP-conjugated goat anti-rabbit antibody (1:10,000; Jackson ImmunoResearch Laboratories, West Grove, PA, USA) for 1 hour at room temperature. The bands were acquired by enhanced chemiluminescence (GE Healthcare Biosciences, Piscataway, NJ, USA), and the blots were scanned and quantified using TotalLab Quant analysis software (TotalLab Limited, Newcastle Upon Tyne, England) and the result was expressed as the ratio of target gene immunoreactivity to GAPDH immunoreactivity.

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.
