calcein

基本解释

The free calcein was well separated from the vesicles with ultrafiltration method.
不同截留分子量的超滤膜对钙黄绿素的膜透过率没有影响；
Methods：Ultrafiltration was applied to separate the free calcein from the vesicles.
方法：采用超滤法分离囊泡与钙黄绿素；
Conclusion:We should use the calcein methods in the calcium content determination for Gypsum.
结论:石膏的含量测定应采用钙黄绿素法。
The outlines are as follows:1 In a Clark-Lubs buffer at pH 3.5, the absorptivity of calcein is reduced by the interaction of HSA and calcein.
1 在pH=3.;5的Clark-Lubs缓冲溶液中;钙黄绿素与人血清白蛋白形成复合物;导致钙黄绿素吸光度降低。
Aggregated Aa 1-40 may induce the leakage of ANTS and Calcein in a dose-dependent manner, but soluble Aa 1-40 had no such effect.
聚集的A茁1-40能够诱导包裹在脂质体内的ANTS/DPX,Calcein的漏出,但不能诱发Dextran(FD-4)的漏出,并初步估算出聚集的A茁1-40在膜上能产生孔径为13-18?的小孔,而可溶的A茁1-40无此作用。
