A Study on Stabilization of α - amylase by Dextrans with Hydrophobic Groups

含疏水基右旋糖酐对α-淀粉酶的稳定作用

The retention of proteins is higher than that obtained by glycols and dextrans .

膜对蛋白的截留率高于它对聚乙二醇和葡聚糖的截留率。

Results : The Mn , Mw and molecular weight distribution curves ( cumulative weight fraction distribution curves ) were obtained by GPC software from the calibration curves which were made by standard dextrans .

示差折光检测器。结果：利用GPC软件处理，得到莫海林的数均、重均分子量和分子量累积重量分布曲线。

Seleno reaction products of self made Astragalan ⅱ( a kind of D dextrans , 12 300 ) and market sold D dextran ( 15 000 ~ 20 000 ) were found to have immunological effects on mice .

对自制黄芪多糖Ⅱ（其为D－葡聚糖，分子量约为12300）和市售D－葡聚糖（分子量在15000～20000）进行硒化反应后，用在小鼠上具有各种免疫作用。
