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® Monoclonal Antibody mix 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. A detailed protocol and Limited Use License allowing the use of the patented PTMScan® method are included with the kit.


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

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.

PTMScan® Multi-Pathway Enrichment Kit introduces Cell Signaling Technology's PTMScan® Direct Multi-Pathway proteomics service to the end user in a convenient and easy-to-use kit format. Based on the patented PTMScan® method, the kit includes an array of site-specific antibodies conjugated to protein A beads for peptide immunoaffinity purification. The kit is designed for the screening, discovery, and quantitation of thousands of proteins and phosphorylation sites on hundreds of critical signaling proteins spanning multiple signaling pathways. These include cell cycle and checkpoint control, PI3 Kinase and Akt signaling, MAPK and JNK cascades, T-cell and B-cell receptor signaling, as well as some housekeeping targets. The kit can also be used as the enrichment reagent for customized targeted assays by including heavy isotope-labeled synthetic peptides to a subset of validated targets.
