The ability to adequately measure the phosphorylation state of a protein has major biological as well as clinical relevance. Due to its variable nature, reversible protein phosphorylations are sensitive to changes in the tissue environment. Stabilizor T1 is a system for rapid inactivation of enzymatic activity in biological samples. Enzyme inactivation is accomplished using thermal denaturation in a rapid, homogeneous, and reproducible fashion without the need for added inhibitors. Using pCREB(Ser133) as a model system, the applicability of the Stabilizor system to preserve a rapidly lost phosphorylation is shown.
