The reversible thermal denaturation of apo α-lactalbumin and lysozyme was monitored via measurement of changes in absorbance and ellipticity in the presence of varying concentrations of seven mono- and oligosaccharides: glucose, galactose, fructose, sucrose, trehalose, raffinose, and stachyose. The temperature

We reported an improved combinatorial approach for identifying site-specific O-glycosylation using both glycan cleaved and non-cleaved methods. In this approach, a non-reducing β-elimination kit coupled with non-specific enzymes performed efficient digestion, O-glycan cleavage, and partial dephosphorylation without significant side reactions
