Summary of intralaboratory and interlaboratory variation for metrics for three LTQ and three LTQ-Orbitrap instruments in six replicate analyses of a tryptic digest of CPTAC yeast reference proteome in CPTAC Study 5. Summary of intralaboratory and interlaboratory variation for metrics for three LTQ and three LTQ-Orbitrap instruments in six replicate analyses of a tryptic digest of CPTAC yeast reference proteome in CPTAC Study 5. The instruments labeled LTQ are all LTQ model instruments; the instruments labeled Orbis include two LTQ-Orbitraps and one LTQ-XL-Orbitrap. Metrics are grouped by system category and ranked by code for comparison between panels. Intralaboratory variation in %dev for each metric and variation in %dev are shown in a. b and c show interlaboratory variation in metrics for LTQ and Orbitrap instruments, respectively. IQ, interquartile; pep, peptide; IDs, identifications; med., median; ID'd, identified; fract., fraction; num, number. Paul A. Rudnick et al.
