The Unbiased Discovery Working Group attempted its first use of a Standard Operating Procedure (SOP) in re-analyzing the trypsin-digested NCI-20 mixture at sites that had installed Thermo LTQ or Orbitrap instruments. Three "1B" samples were provided to each participating laboratory on two successive weeks. The use of an SOP controlled the rate of MS/MS acquisition but proved less effective in generating similar identified peptide counts across instruments.
