PTMScan® Proteomics Services from Cell Signaling Technology (CST) employ proprietary methodologies for antibody-based peptide enrichment combined with tandem mass spectrometry for quantitative profiling of post-translational modifications (PTMs), including phosphorylation, ubiquitination, methylation and acetylation.

PTMScan® Discovery Services

PTMScan® Discovery Services are intended as a discovery-mode proteomics technology for identifying and quantifying post-translational modifications in biological model systems.

Overview of PTMScan Discovery >>

Why consider antibody enrichment for studying phosphorylation?

  • Focused discovery of phosphosites based on amino acid (S/T/Y) or motif of interest
  • Increased coverage of lower occurring phosphorylation events compared to IMAC
  • View data showing complementarity between antibody enrichment and IMAC

PTMScan® Direct Services

PTMScan® Direct Services are intended as a targeted-mode proteomics screening technology with defined assay endpoints, allowing focused studies on critical signaling nodes.
