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. WebWe report a technique for detecting protein phosphorylation that involves isoelectric focusing in a vertical mini-gel format followed by immunoblot detection of the target …

How to detect protein phosphorylation? ResearchGate
WebAug 23, 2013 · CLK1 induces a unique gel shift in SRSF1 that is not the result of enhanced Arg-Ser phosphorylation but rather is the direct result of the phosphorylation of several Ser-Pro dipeptides. These prolines are important for binding and phosphorylation of the SR protein by CLK1 but not for the SRPK1-dependent reaction. WebBefore further analyses, a gel shift of protein band on SDS/PAGE (T = 10% for p-Tau441 and T = 12% for p-TauF8) allowed a qualitative control of protein phosphorylation.
