1. Influence of MS measurement conditions on the deviation factors between the estimated and measured concentrations of 46 proteins in neuro2a cells.A, QSTAR with faster scan cycle (0.55 s for each MS/MS scan).
Influence of MS measurement conditions on the deviation factors between the estimated and measured concentrations of 46 proteins in neuro2a cells.A, QSTAR with faster scan cycle (0.55 s for each MS/MS scan). B, QSTAR with slower scan cycle (1.5 s for each MS/MS scan). C, LCQ with slower scan cycle (1.2 s on average for each MS/MS scan). D, LTQ with faster scan cycle (0.38 s on average for each MS/MS scan). E, multidimensional LC-MS/MS with LTQ (five fractions). F, multidimensional LC-MS/MS with QSTAR and LTQ.
