    Protocol

    Product Description

    PTMScan® Technology employs a proprietary methodology from Cell Signaling Technology (CST) for peptide enrichment by immunoprecipitation using a specific bead-conjugated antibody in conjunction with liquid chromatography (LC) tandem mass spectrometry (MS/MS) for quantitative profiling of post-translational modification (PTM) sites in cellular proteins. These include phosphorylation (PhosphoScan®), ubiquitination (UbiScan®), acetylation (AcetylScan®), and methylation (MethylScan®), among others. PTMScan® Technology enables researchers to isolate, identify, and quantitate large numbers of post-translationally modified cellular peptides with a high degree of specificity and sensitivity, providing a global overview of PTMs in cell and tissue samples without preconceived biases about where these modified sites occur (1).

    Background

    Carboxymethyl lysine (CML) and carboxyethyl lysine (CEL) are two protein post-translational modifications that arise from non-enzymatic pathways and represent examples of advanced glycation end products (AGEs) (1). The association between CML/CEL levels with glucose and oxidant stress levels underlies the use of these modifications as biomarkers for various disease conditions, including diabetes and osteoporosis (2). The Maillard reaction between monosaccharides and lysines can form a Schiff base intermediate that rearranges to become CML/CEL. In addition, fragmentation of the Schiff base intermediate and oxidation of amino acids and polyunsaturated fatty acids produce reactive species, such as glyoxal and methylglyoxal, which react with lysine to form CML/CEL. While CML/CEL exists as free and protein-incorporated forms, in vitro treatment with protein-incorporated CML/CEL in particular induces diverse effects, including reduced serotonin release in gastric cells, impaired calcium homeostasis in cardiac cells, and increased reactive oxygen intermediates in endothelial cells (3-5). These processes depend on receptor for AGE (RAGE) signaling.
