A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Nanoflow liquid chromatography/mass spectrometry (nanoLC/MS) has become a current tool in proteomics applications increasingly used in the search for new biomarkers. A new integrated microfluidic device (HPLC-Chip), coupled to ion trap mass spectrometry (ITMS), appears as an innovative and robust tool for improving the identifications commonly performed by nanoLC/MS/MS. We tested this device for the identification of proteins obtained from two-dimensional gel electrophoresis or chromatography. The chip allows the measurement of reproducible retention times that, in association with m/z ratios, was found useful for identifying peptide sequences without ambiguity. A sensitivity increase of a factor of at least 5-fold is obtained compared to the results obtained previously in our laboratory by conventional nanoLC/MS/MS on the same ion trap. We conclude that this recently available microfluidic device can be a valuable tool during biomarker discovery programs, particularly identifying low-abundance proteins.
