Application
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。
Analysis Note
RNAse B糖蛋白标准品已经过高度纯化,以去除污染的RNaseA。
Other Notes
牛胰腺核糖核酸酶 B 是一种糖蛋白,仅含有 N-连接聚糖。它是由单个结构域组成的球状蛋白,与作为非糖基化核心形式的核糖核酸酶A(RNase A)在混合物中以较少成分的形式天然存在。RNase B 在 Asn 34 处含有一个糖基化位点,在该位点有 5-9 个甘露糖残基连接到壳二糖核心,即 Man 5-9 GlcNAc 2 。由于 Asn 34 糖基化的异质性,RNase B 以 5 种糖基化变体形式存在,分子量约为 15 kDa。

N-glycosylation is a complex post-translational modification with potential effects on the efficacy and safety of therapeutic proteins and known influence on the effector function of biopharmaceutical monoclonal antibodies (mAbs). Comprehensive characterization of N-glycosylation is therefore important in biopharmaceutical development. In
