WebJan 26, 2006 · An alternative to these methods is detection of a gel mobility shift in the protein by immunoblot analysis. Phosphorylation sometimes results in the protein migrating at a higher, apparent molecular mass. The shift clearly does not result from the mass of the phosphate itself (0.08 kDa), which is far too small to alter the migration of a protein.
