Our nanoLC-chip-QTOF can be used with different chip lay-outs, depending on the application. For peptide and glycopeptide profiling reversed phase C18 chips are available, for whole protein analysis C8 chips and for glycan profiling Carbograph chips. Several protocols for glycomics and glycoproteomics applications are available.
What is glycomics?

-
The high mass resolution of the QTOF allows annotation of protein glycoforms by C8-chip-QTOF.

Whole protein glycoprofiling
The high mass resolution of the QTOF allows annotation of protein glycoforms by C8-chip-QTOF. We have recently established a method for analysis of the glycoforms of immunopurified serum transferrin (~80kDa), showing a variety of different glycan structures. -
N-glycans enzymatically released from glycoprotein preparations and biological fluids (e.g. serum, liquor) can be separated and analyzed using the Carbographchip.

Analysis of selected glycopeptides is possible on the C18 chip after off-line enrichment of glycopeptides.
-
These methods are part of our current and future developments.

Analysis of free glycans (oligosaccharides) is facilitated by labeling with a fluorescent tag for HPLC or mass spectrometry or with an isotopic derivative for quantitative measurements.

Glycan (fluorescence) labeling
Analysis of free glycans (oligosaccharides) is facilitated by labeling with a fluorescent tag for HPLC or mass spectrometry or with an isotopic derivative for quantitative measurements. Both methods are available and are being applied to the analysis of free oligosaccharides in urine.
