Large-Scale EMSL Research

This capability-development project will provide PNNL and DOE with a unique live / in-situ metabolomics capability for microbial bioenergy development. The technology will be applicable for the…

Application of High-Throughput Proteomics

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Mary Lipton

The understanding of how cells function at the systems level will greatly benefit from the development of new approaches capable of making global measurements of protein expression (proteome). The…

Integrated NMR/SIP technologies for the functional and structural characterization of microbial communities

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Johannes Scholten

Project type

Large-Scale EMSL Research

We propose to combine stable isotope probing (SIP) of DNA (SIP-DNA) with real-time on-line SIP-nuclear magnetic resonance (SIP-NMR) analysis of microbial community metabolism. SIP-NMR provides access…
