Studies on Identification of Seven Snake-drugs by Iso-electric Point 7种蛇类药材的等电点鉴别研究
The ionic strength of the supporting electrolytes affects the value of the electrophoretic mobility, but does not change the IEP ( Iso-electric point) of a given kind of particle. 支持电解质的离子强度影响淌度的大小,但不改变等电点(IEP)。
The densities of the surface groups, which are same in charging mechanism but opposite in charge sign, are symmetrically distributed in the main about the iso-electric points in x-shape in the range of applied pH values; 荷电机理相同、电性相反的表面组分的浓度在所用pH范围内对iep基本上呈x形对称分布;
More than 13 acidic and 14 basic bands may be distinguished with an improved iso-electric focus electrophoresis system by adjusting Ampholine ratios. 通过调整两性电解质比例对现有等电点聚焦电泳分析法进行改良,可将谷蛋白酸性亚基和碱性亚基分别分划为13和14条多肽带。
The substance composition variance of the bacteria cell walls, the distinction of the molecular composition and the structure of peptidoglycan which is the specific composition of bacteria cell walls, the distinction of acid dissociation and iso-electric point of different bacteria; 以及不同细菌细胞壁的物质组成差异,构成细胞壁特征性物质&肽聚糖分子组成和空间结构存在的差异,不同细菌酸式解离以及等电点的差异;
