PTMScan® Direct Proteomic Services

PTMScan Direct Services Overview

PTMScan® Direct technology is a mass spectrometry-based antibody array that combines antibody enrichment of post-translationally modified (PTM) peptides from defined pathways with LC-MS/MS. It allows identification and quantification of hundreds to thousands of known protein targets within a specific pathway in response to a treatment or disease state in a single LC-MS/MS run.

Follow-up of many of the candidate proteins identified in PTMScan Direct services can be performed using modification state-specific and total protein antibodies from CST, which are produced and validated in-house for multiple applications.
