Product Usage Information

Cells are lysed in a urea-containing buffer, cellular proteins are digested by proteases, and the resulting peptides are purified by reversed-phase, solid-phase extraction. Peptides are then subjected to immunoaffinity purification using a PTMScan® antibody conjugated to protein A agarose beads. Unbound peptides are removed through washing, and the captured PTM-containing peptides are eluted with dilute acid. Reversed-phase purification is performed on microtips to desalt and separate peptides from antibody prior to concentrating the enriched peptides for LC-MS/MS analysis. CST recommends the use of PTMScan® IAP Buffer #9993 included in the kit. An alternate PTMScan® IAP Buffer Plus Detergent #9992 which may reduce nonspecific interactions is available separately. A detailed protocol and Limited Use License allowing the use of the patented PTMScan® method is included with the kit.


Storage: Antibody beads supplied in IAP buffer containing 50% glycerol. Store at -20°C. Do not aliquot the antibodies.

Product Description

PTMScan® Technology employs a proprietary methodology from Cell Signaling Technology 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® 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).
