intrinsic fluorescence meaning in English
内荧光
Examples
- In this article , bioaerosol mass spectrometry , an instrument for real - time detection of bioaerosols using simultaneous measurement of particle aerodynamic size and intrinsic fluorescence , real - time qpcr , and fcm / fl were discussed
生物性气胶质谱侦测仪(指即时侦测生物性气胶及微粒气动直径之仪器) 、即时定量酵素聚合反应技术、萤光染色配合萤光显微镜将于本文中讨论之。 - To detect whether crosslinking reaction influence the fluorescence properties of the samples , oxygen - evolving psil core complexes were treated with five crosslinking agents at different concentration , then the chlorophyll fluorescence emission , excitation , and intrinsic fluorescence spectra of these samples were measured . the results showed that both chlorophyll fluorescence and intrinsic fluorescence of oxygen - evolving psil core complexes were altered by the crosslinking reaction . the maximum chlorophyll fluorescence band at 682 nm decreased and the intrinsic fluorescence emission intensity at 308 nm and 328 nm either increased or decreased
结果表明：交联处理对psll放氧核心复合物叶绿素荧光和内源荧光都有影响，引起682urn处叶绿素荧光强度的降低、 308urn或328urn处蛋白质内源荧光强度的增大或减小，并与处理时所用交联剂的浓度、交联剂的亲疏水性和交联臂长相关。 - In order to investigate the effects of ph , temperature , naf and bivalent cations on the conformation of the phosphatase in solution , we monitored the difference of intrinsic fluorescence of the phosphatase and compared changes of the enzyme activity under those conditions . the tertiary structure loosed and the intensity of fluorescence decreased below ph 6 . 0 . the intensity of fluorescence was lowest at ph 5 . 0 and the tertiary structure was reconstructed as the solution ph was increased
其中在ph5 . 0及以下时，蛋白质的三级结构变得松散，荧光强度下降， ph5 . 0时尤为显著，而当溶液ph高于5 . 0时(酶的最适ph ) ，样品的荧光发射强度明显增加，表明酶蛋白受溶液酸碱度的影响，构象发生部分变化，部分trp残基向疏水环境移动，其三级结构得到恢复。
