I want to measure ubiquitination following IP of my proteins of interest. Does anyone have experience with ubiquitin antibodies that work well in skeletal muscle tissue or L6 muscle cells?
They are quite specific, but of course depends on the protein amount,success of your IP etc. We performed IP from C2C12 cells, detection with anti-Ub 1/5000 in 3 milk PBS-T, let say over night. Secondary 1/10000, 45min.
Check the conditions firstly on your input,before IP. For us 25uq of proteins in the lane was quite enough to see a polyubiquitylation patterns.
