dc.description.abstract | The microcapillary liquid chromatography (mLC)/tandem mass spectrometry (MS/MS) system has become a prevailing analytical platform in proteomics. Typical proteomic studies aimed at proteomewide identification of peptides and proteins rely heavily on producing an accurate and reproducible solvent-composition gradient throughout microcapillary separation columns to improve LC separation. With the recent advent of targeted proteomic approaches utilizing the LC retention time as a physicochemical parameter for peptides, high reproducibility of LC separation additionally becomes an important factor. In this study, column temperature elevation is utilized to improve reproducibility and separation efficiency of the mu LC-MS/MS system. The simple incorporation of a semi-rigid gas line heater allowed precise control of the temperature of microcapillary columns longer than 70 cm, up to 60 degrees C. Tryptic enolase peptides were used as a standard sample to evaluate the effect of the controlled temperature elevation on the peptide separation efficiency and reproducibility. In addition to the increased reproducibility in peptide elution time due to the controlled column temperature, the temperature elevation resulted in a decrease in the column operation pressure, which, in turn, allowed a higher solvent flow-rate to be employed using the same LC pumps, leading to further improvements in the performance of mLC systems. | - |
