Western Blot Analysis of Inflammatory Signaling

Check if the same lab product or an alternative is used in the 5 most similar protocols
Whole protein in the serum was collected using a whole-protein extraction kit (Nanjing KeyGEN Biotech, Nanjing, China) according to the manufacturer’s instructions. The protein concentration was measured using a bicinchoninic acid kit (Nanjing KeyGEN Biotech). The different proteins were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and transferred onto polyvinylidene difluoride membranes (Bio-Rad). The membranes were blocked in Tris-buffered saline and Tween 20 (TBST) blocking buffer that contained 5% nonfat dried milk for 2 h at room temperature and immunoblotted with primary specific antibodies (anti-TLR4, anti-TRAF6, anti-TAK1, IκB-α, p-IκB-α, anti-NF-κB (p65), anti-p-NF-κB (p-p65), and anti-β-actin (Abcam, UK). After washing with TBST, the strips were incubated with horse-radish peroxidase-conjugated goat anti-mouse IgG (HuaAn, Hangzhou, China). Proteins were detected using a SuperSignal™ West Femto Maximum Sensitivity Substrate (Thermofisher) and visualized using a ChemiDoc™ MP Imaging System (Bio-Rad).

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.
