Armed with survey software, ProteoMonitor embarked on a guided tour of the protein mass spectrometry landscape last month. We conducted an e-mail survey of 2,000 readers of GenomeWeb’s proteomics and mass spec news channel and received reponses from 173 of them. The survey results have a ±7.6 percent maximum sampling error at a 95 percent confidence level. The data collected represent a measure of how users are applying mass spectrometry to protein analysis, and what they think of the tools they’re using.
