Collaborative Protein Technology Resource (CPTR)

Is an open core supported by the Office of Science and Technology Resources (OSTR) dedicated to establishing and implementing cutting-edge molecular profiling technologies to facilitate discovery, translational and clinical research.

Project Management


At the Nanoscale Protein Analysis section of CPTR, we offer expertise and provide state-of-the-art technologies to accommodate the needs of CCR/NCI/NIH investigators.

Simple Western

An automated capillary immunoassay system for precise and accurate measurement of proteins and respective post-translational modifications in a format that is applicable to very small sample sizes.

CODEX (CO-Detection by indEXing)

An immunofluorescence imaging platform for highly multiplexed (30-50 plex) IHC-analysis with single-cell resolution and retention of spatial context. It allows comprehensive in-situ protein profiling with multi-parametric readouts from a single tissue section.
