Cím:	Effect of the elapsed time between sampling and formalin fixation on the N-glycosylation profile of mouse tissue specimens / Donczo Boglarka, Kiraly Gabor, Guttman Andras

Megjegyzések:	Formalin-fixed, paraffin-embedded (FFPE) samples are generally used for histology-study, however, they also possess importantmolecular diagnostics information. While it has been reported that the N-glycan moieties of glycoproteins is not affected by the FFPE process, no information is available about the effect of the elapsed time between sampling and fixation on the resulting N-glycosylation profile. In this study, lung, brain, heart, spleen, liver, kidney, and intestine mouse tissue specimens were used for N-glycan profiling analysis and the elapsed sampling time effect was investigated with the lung tissue. N-glycan extraction from the tissue samples was performed by glycoprotein retrieval from the FFPE specimens using radioimmunoprecipitation assay (RIPA) buffer followed PNGase F digestion. The released oligosaccharides were fluorophore labeled and analyzed by capillary electrophoresis-laser induced fluorescent detection (CE-LIF). N-glycosylation profiles of freshly collected lung-tissue samples (zero time point), as well as 1 and 2 h after sampling were compared by carbohydrate profiling and exoglycosidase treatment based deep glycomic analysis. It was found that up to two hours of room temperature storage of tissue specimens apparently did not cause changes in the N-glycosylation profiles of complex carbohydrates, but resulted in considerable decrease in the amount of linear glucose oligomers and high mannose type glycans present in the samples.
