Assay Portal

The CPTAC Assay Portal serves as a centralized public repository of "fit-for-purpose," multiplexed quantitative mass spectrometry-based proteomic targeted assays. Targeted proteomic assays eliminate issues that are commonly observed using conventional protein detection systems.

The goal of the portal is to widely disseminate highly characterized proteomic assays to the global research community, with access to SOPs, reagents, and assay characterization/validation data in support of the National Institutes of Health’s Rigor and Reproducibility Principles and Guidelines.  Targeted mass spectrometry assays are characterized according to the CPTAC assay characterization guidelines. The portal is also designed to bring together biologists seeking to ask hypothesis-driven questions about the proteome they study with analytical chemists equipped to perform targeted proteomic assays.
