5-TAMRA Picolyl Azide|5-TAMRA Picolyl N3
5-tamra吡啶甲基疊氮是一種先進(jìn)的熒光探針,采用銅螯合基序提高銅的有效濃度(我)在反應(yīng)位點(diǎn)。螯合作用的吡啶甲基疊氮基團(tuán)在反應(yīng)部位提高銅的有效濃度是如此之大,導(dǎo)致高達(dá)40倍的信號(hào)強(qiáng)度的增加。此外,代替?zhèn)鹘y(tǒng)的5-tamra疊氮化物5-tamra吡啶甲基疊氮的使用允許至少十倍減少銅催化劑的濃度不犧牲標(biāo)記效率。
雖然5的混合異構(gòu)體(6)- TAMRA是*,經(jīng)常使用的紅色熒光染料染色的蛋白質(zhì),肽和核苷酸標(biāo)記TAMRA混合異構(gòu)體可能麻煩由于顯著的信號(hào)在HPLC純化展寬。肽和核苷酸標(biāo)記與一個(gè)單一的異構(gòu)體發(fā)生通常會(huì)得到更好的分辨率在HPLC純化,往往在接合過(guò)程中需要。
總之,一個(gè)甲基吡啶基團(tuán)為疊氮探針的引入在炔烴的檢測(cè)靈敏度大幅提高。這對(duì)于探測(cè)低豐度目標(biāo)或顯著提高信號(hào)強(qiáng)度是特別有價(jià)值的。
