Phosphorylation gel shift
WebJun 23, 2016 · Classical methods for studying protein phosphorylation. A number of classic methods exist for this, the most common of which is the utilization of phosphomimetic residues. The phosphorylated residue of interest is mutated to a negatively charged residue, aspartate or glutamate, imparting the negative charge associated with phosphorylation. 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 …

Web2 gel shift. The MAPK kinase inhibitor, PD 98059 suppressed A23187-induced MAPK activation and cPLA 2 gel shift but had little effect on arachidonic acid release. These results indicate that in macrophages a transient increase in [Ca21] i and sus-tained phosphorylation of cPLA 2 can act together to promote arachidonic acid release but … WebFeb 10, 2024 · Things you could try to detect the phosphorylation: Use phospho-specific antibodies. These are often expensive, tricky to use or just not available, but this is the …
WebShifts can occur due to intrinsic net charge, post-translational modifications, aggregation, degradation, the existence of multiple protein variants, and precursor processing. An understanding of these factors can assist in troubleshooting, as well as provide further information on protein structure and function. WebFeb 10, 2024 · I agree that observing a shift for a 150 kDa protein may be difficult, but shifts due to phosphorylation can be seen for some proteins on SDS-PAGE gels. See for example this paper. – tyersome Feb 10, 2024 at 19:45 @tyersome I guess it is possible in some cases even though it normally shouldn't happen - I edited the answer.

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. canning 101 recipesWebMobility shift detection of phosphorylation on large proteins using a Phos-tag SDS-PAGE gel strengthened with agarose.
