compound introduction
RNase B是带有PNGase F的优选底物，用于证明使用SDS-PAGE或MALDI-MS进行N联去糖基化。PNGase F的活性通常使用RNase B通过监测去糖基化后在12%凝胶中明显的迁移率变化来测定。蛋白质组学级RNase B在酶消化和随后的纯化后已被用作N-聚糖的来源。它也被用作糖蛋白标准品。 RNase B is a preferred substrate with PNGase F for demonstration of N-linked deglycosylation using SDS-PAGE or MALDI-MS. The activity of PNGase F is routinely assayed using RNase B by monitoring the pronounced mobility shift in 12% gels after deglycosylation. Proteomics Grade RNase B has been used as a source of N-glycans following enzymatic digestions and subsequent purification. It has also been used as a glycoprotein standard.
