Phospho peptides are essential tools to study phosphorylation by protein kinases in many eukaryotic cellular processes. Use of such peptides can determine how a cell responds to extracellular signals and how they produce intracellular responses. The specificity of the post-translational phosphorylation is critical in this kind of research. In addition, phospho-specific antibodies made from phospho peptides are used to detect changes in the phosphorylation of specific proteins at a specific site. CPC Scientific has extensive experience not only in labeling peptides with phosphorylated Ser, Thr, and Tyr, but also in producing multiple phosphorylated amino acids within the same peptide.
