Pneumatic tube system induced haemolysis: assessing sample type susceptibility to haemolysis.

abstract：BACKGROUND:It is important to explain target proteins for the understanding of the pathogenesis of vitreoretinal diseases. In a previous study, we identified more than 100 proteins including seven angiogenic-modulated factors in vitreous humours (VHs). Although there have been many reports of expressed protein profiles...
