Hi Guys, I am working on western blotting of tight junction proteins in mice colon tissue. Currently, I suspect my problem is low protein content in the prepared lysate.
I am just wondering whether there will be significantly protein degradation in mice colon tissue during the storage at -80 for over 6 month?
After I kill the mice, I took the colon tissue out immediately and put in liquid nitrogen then transferred into -80 C. All the operation is on ice.
