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…

Accuate size measurement of bacterium SAR-11

Lead Institution

Oregon State University

Principal Investigator

Stephen Giovannoni

Project type

Exploratory Research

SAR-11 appears to be the dominant microorganism in the upper ocean, and is one of the smallest bacteria. The objective is to obtain an exact measurement of its size, without producing artifacts…
