PTMScan® Services

Experienced CST scientists perform qualitative and quantitative profiling of post-translational modifications (PTMs) using proprietary proteomic methods that combine antibody enrichment of PTM-containing peptides with LC-MS/MS. The PTMScan® team works with you from project planning to delivery of a comprehensive data package that includes:

  • Qualitative/quantitative tables
  • Informatics tables
  • Microsoft Powerpoint® summary
  • Microsoft Word® guide to prioritizing follow-up candidates
PTMScan Services Workflow

Services Offered

  • Immuno-Parallel Reaction Monitoring (iPRM)

    iPRM is a targeted proteomic method that combines the specificity of mass spectrometry with the throughput of an immunoassay. It provides absolute quantitation of low-level proteins and post-translational modifications. It’s also a multiplexed technique, so you’ll get more data with a single experiment. iPRM assays use best-in-class CST antibodies and are developed and validated by our expert scientists, so you’ll get data you can trust, fast.

  • TMT10plex™ Total Proteome

    TMT10plex™ Total Proteome profiling service provides accurate global profiling of protein abundance in cells and tissues, using multiplexed sample labeling with Tandem Mass Tags™ (TMT™) and liquid chromatography tandem mass spectrometry (LC-MS/MS).

  • PTMScan® Discovery

    PTMScan® Discovery is used to identify and quantify hundreds to thousands of PTM peptides.

  • Immobilized metal affinity chromatography (IMAC)

    IMAC captures negatively charged phosphopeptides using positively charged metal ions and is complementary to phosphorylation analysis by PTMScan® Discovery.

  • PTMScan® Direct

    PTMScan® Direct is a mass-spectrometry-based antibody array used to quantitatively assay the activity of components of known signaling pathways across cell lines or treatments.

  • KinomeView® Profiling

    KinomeView® Profiling is a western blot prescreen that uses the same PTM and motif antibodies available for PTMScan Discovery.

  • Global Proteome Service

    Quantification of protein levels across cell lines or treatments without enrichment for PTM-containing peptides.

  • Ingenuity® Pathway Analysis

    Mapping of PTMScan results onto canonical pathways and new interaction networks using Qiagen’s Ingenuity® Pathway Analysis (IPA) software.
