關(guān)于在表達(dá)蛋白和GFP蛋白之間的linker
|
|||
| 各位好,我最近在做膜蛋白的表達(dá),在構(gòu)建載體的時(shí)候我在膜蛋白的C端還加了GFP指示蛋白,但是在誘導(dǎo)表達(dá)后,根本看不到菌發(fā)出綠色熒光,而我只表達(dá)GFP時(shí)卻能看到菌是綠色的,我在構(gòu)建載體的時(shí)把膜蛋白和GFP直接連在一起了,中間沒有加linker regions,我想問一下各位,我的菌株看不出綠色的原因是不是我沒有加一個(gè)linker的原因呢,如果有做過這方面的大俠是不是可以知道一下我呢,多謝各位! |

protein of interest surely weakens fluorescence of GFP with linker or without linker. i have ever made experiment about expression of fusion protein including GFP, the fusion protein including GFP can emit green fluorescence although its green fluorescence is weaker than that of control. but the fusion protein in my experiment is located at the cytoplasm, and your protein occured in the membrane, I don`t know whether location of protein including GFP effects fluorescence emission or not. |
