聚蔗糖

用改良胶原酶消化技术和聚蔗糖密度梯度离心方法将大鼠胰岛从胰腺分离，按Sun等的方法用海藻酸和聚赖氨酸等予以微囊化。

Rat pancreatic islets were microencapsulated with , sodium alginate and poly-lysine , according to Sun 's method after being isolated from pancreatic tissue using modified collagenase digestion and Ficoll density gradient separation .

用改良胶原酶消化技术，聚蔗糖密度梯度离心及手法挑拾方法从大鼠胰腺成功地分离出完整的胰岛。

This paper reports the successful isolation of islets of Langerhans from the rat pancreas using a modified collagenase digestion , Ficoll density gradient separation and hand-picking technique .

人血SOD分别经右旋糖苷及聚蔗糖两种修饰剂共价修饰后，仍保留其紫外、荧光吸收特性及SOD的酶活性。

The modified hSOD still remains native SOD activity with similar characteristics of ultraviolet and fluorescent absorption .

可用Langmuir吸附等温式描述聚蔗糖微球对牛血清白蛋白（BSA）的吸附行为。

Langmuir formula was used to describe adsorption of bovine serum albumin ( BSA ) on PS microspheres .

聚蔗糖多孔微球对BSA的饱和吸附量随羟基含量的增大而增大，最高可达98.54mg/g，高于相同交联剂用量的凝胶微球。

Qm increased with hydroxyl content , and reached its maximum at 98.54mg / g , which was much higher than gelatinous PS microspheres .

羟基含量也是影响聚蔗糖多孔微球吸附量的主导因素。

It is revealed that hydroxyl content was also the key factor to q m of porous PS microspheres .
