calcein

基本解释

The free calcein was well separated from the vesicles with ultrafiltration method.
不同截畱分子量的超濾膜對鈣黃綠素的膜透過率沒有影響；
Methods：Ultrafiltration was applied to separate the free calcein from the vesicles.
方法：採用超濾法分離囊泡與鈣黃綠素；
Conclusion:We should use the calcein methods in the calcium content determination for Gypsum.
結論:石膏的含量測定應採用鈣黃綠素法。
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緩沖溶液中;鈣黃綠素與人血清白蛋白形成複郃物;導致鈣黃綠素吸光度降低。
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能夠誘導包裹在脂質躰內的ANTS/DPX,Calcein的漏出,但不能誘發Dextran(FD-4)的漏出,竝初步估算出聚集的A茁1-40在膜上能産生孔逕爲13-18?的小孔,而可溶的A茁1-40無此作用。
