透明质酸(hyaluronan, HA)是生物体内最重要、最普遍存在的糖胺聚糖之一,其生物学功能和理化性质与其分子量、分子量分布和链构象密切相关。因此,在化学和临床领域对HA的这些参数进行可靠的表征是至关重要的。本文比较了毛细管粘度法、浓度梯度多角度激光散射法(gc - malls)、粒径排除色谱-多角度激光散射法(SEC-MALLS)、不对称流场流动分选-多角度激光散射法(AFlFFF-MALLS)和水平琼脂糖凝胶电泳(AGE)等不同技术在细菌和动物源透明质酸样品表征中的应用。从产生准确可靠的分子参数的角度讨论了这些技术的优点和局限性。
The biological functions as well as physico-chemical properties of hyaluronan (HA), one of the most important and ubiquitous glycosaminoglycan in various organisms, are closely related to its molecular weight, molecular weight distribution and chain conformation. For this reason it is crucially important to make a reliable characterization of these parameters for HA in both chemical and clinical fields. The present work compared the application of different techniques including capillary viscometry, concentration gradient multiangle laser light scattering (CG-MALLS), size exclusion chromatography-multiangle laser light scattering (SEC-MALLS), asymmetric flow field flow fractionation-multiangle laser light scattering (AFlFFF-MALLS) and horizontal agarose gel electrophoresis (AGE), to the characterization of a range of HA samples of bacterial and animal sources. The advantage and limitation of these techniques were discussed in terms of producing accurate and reliable molecular parameters.
