top-down proteomics

Writing in MCP, the researchers provided a survey of techniques for biologists interested in using multiplexed quantitative proteomics in their research.

The effort, dubbed the National Resource for Translational and Developmental Proteomics, aims to improve on the technology and train others in its use.

According to the researchers, the system could make top-down approaches more widely shareable as well as improve their applicability to clinical work.

Pacific Northwest National Laboratory's Sangtae Kim is taking on the challenges of analyzing top-down proteomic data.

A team led by researchers at Pacific Northwest National Laboratory has devised a streamlined top-down proteomics approach that they have used to profile the pathogen Salmonella Typhimurium.
