Three expression vectors containing mutant gfp which were truncated from 3′ termine were constructed in the present paper.The mutation gfp with different length under the control by T 7 promoter were expressed in E. coli BL21 cells.

本文将突变型 gfp3′末端不同程度地截短，构建成表达载体，在大肠杆菌 BL 2 1中表达了不同长度的绿色荧光蛋白，当其生色基因中 65位 Ser点突变成 Thr，则 GFP的激发波由 396nm增至 4 70 nm，不用 UV激发，仅在自然光源下就可看到强烈的绿色荧光，发光强度增加 6倍，若从 3′端截短 12个氨基酸密码，对发光无影响，但截短 75个氨基酸密码，则激发波长降到 360 nm，发光强度减少 12倍。

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。
