Competitive inhibition ELISA using immobilized rabbit anti-mono-methyl arginine (ICP0801) and mono-methyl arginine-HRP. The IC50 concentration for free mono-methyl arginine (mMeR) is approximately 40-50 ng/mL.
Western blot of human MMRU cells with mono-methyl arginine antibody (ICP0801).
A and B: antibody solution without inhibition;
C and D: competitive inhibition with free mono-methyl arginine.
Fluorescent Staining of MMRU cells
Arginine methylation is a very common post-translational modification that occurs predominantly in the nucleus. The main pool of proteins that are modified possess RNA binding properties. More broadly, arginine methylation has been implicated in a variety of cellular processes, including protein trafficking, signal transduction and transcriptional regulation.
