Western Blot Analysis of Tight Junction and Inflammatory Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total proteins of cells were obtained by RIPA Lysis buffer (Beyotime Biotechnology, Jiangsu, China). The proteins were separated by 10% SDS-PAGE, transferred to polyvinylidene uoride (PVDF) membranes (Invitrogen, Carlsbad, CA, USA), and blocked with TBST containing 1.5% BSA at 26 ℃. After 2 h, the membranes were incubated with anti-ZO-1 antibody (1:1000, Invitrogen), anti-Occludin antibody (1:2000, Abcam), anti-RAGE antibody (1:500, Abcam), anti-NF-kB p65 antibody (1:1000, Abcam) and anti-GAPDH antibody (1:4000, Abcam), respectively, at 4°C overnight. After washed three times, the membranes were incubated with HRP-conjugated goat anti-rabbit secondary antibody (1:500, Abcam) at 37 ℃ for 2 h. The protein bands were visualized with ECL kit (Thermo Fisher Scienti c, Rockville, MD, USA), and images were taken with image lab software (Bio-Rad, Hercules, CA, USA).

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.
