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. WebIn contrast, shifts in the mobility of various phosphorylated species of a high-molecular-mass protein, ataxia telangiectasia-mutated kinase (ATM, 350 kDa), could only be detected in the Tris-AcOH system with a 3% w/v polyacrylamide gel strengthened with 0.5% w/v agarose.
