查询词典 fluorescence

A data acquisition and data analysis software for the fast fluorscence kinetics fluorometer of our laboratory is redesigned and recompiled using assembly and BASIC language. The data acquisition rate in the fast rising part of the fluorescence kinetics curves is one order faster (100μs/point) than the old one. It can measure fluorescence parameters, such as Fo and Fi more accurately for calculation of the relative content of inactive PSⅡ, etc.

The results indicated that the content of cytosolic CaM in cells treated with exogenous Ca2+ has increased indistinctively, while fluorescence intensity in cells treated with TFP decreased. So we believed that exogenous Ca2+ has little effect on the expression of CaM. High concentration of TFP can enter yeast cells and combine to CaM to make it inactive, which is the reason that TFP restrain the growth of yeast cells. 5mmol/L EGTA could completely arrest the cell proliferation of MFP7 after 28h, when the fluorescence intensity in cells wasobviously increased with flow cytometry and LSCM.

被较高浓度TFP处理过的MFP7胞内荧光强度则相对较弱，推测是因为TFP进入胞内与CaM结合从而使其失活，这也是高浓度TFP抑制酵母细胞增殖的原因。5mmol／L EGTA处理28h左右后，酵母细胞的生长被抑制在G1晚期，此时通过细胞流式法和在激光扫描共聚焦显微镜下观察到胞内荧光强度显著高于对照，说明CaM的表达水平在G1后期开始上升；回加10mmol／L Ca~(2+)处理24h后，细胞开始恢复生长，细胞流式法测定胞内荧光强度有所下降，表明多数细胞完成G1／S转换，进入生长对数期。
