Post-translational modification, especially phosphorylation of proteins critical for the biological function of proteins . It plays an important role in many key regulatory mechanisms of life phenomena such as signaling, cell cycle, proliferation, metabolism, growth & development and cancer mechanisms.
Phosphorylation process is usually the addition of a phosphate (PO4) group to a protein, commonly at a serine (S), threonine (T) or tyrosine (Y) residue via the action of a kinase. Phosphorylation-Specific Antibody can discriminate between the phosphorylated and the non-phosphorylated state of a protein. It is one of the most frequently asked for types of PTM specific antibodies.
Short cycle, low price

Protein phosphorylation levels are often associated with protein activity, many signaling pathway proteins cause a series of cellular responses by altering their phosphorylation levels after some stimulation, but their protein content does not change much.
Phospho-specific antibody, Prepared against a specific phosphorylation site to detect the changes in the functional state of the protein (enhanced or decreased phosphorylation level) when the cell is stimulated.
Non-phospho-specific antibody, it mainly detects the protein expression level, tissue distribution or cell localization in tissues or cells, and can also be used as an internal reference for changes in phosphorylation level.
