CY5-SE(Cy5 NHS Ester)|1032678-42-4
CY5 NHS ester是用于標記多肽、蛋白和寡核苷酸的氨基基團的活性染料。在標記反應中該染料需要少量的有機共溶劑(如DMF,DMSO)。對于可溶性蛋白、各種各樣的多肽和寡核苷酸而言,這種染料是非常理想而且成本低廉的。該染料在有機溶劑對小分子物質(zhì)的標記也是非常有效的。對于更多的精細目標物,如易降解蛋白,如果DMF或DMSO會對其有影響,可以考慮water-soluble Cy5 NHS ester(水溶性Cy5 NHS ester染料),因為它們不需要有機溶劑助溶,而且具有和熒光染料類似的性質(zhì)。
在過去的幾年里,CY5熒光團已經(jīng)成為生命科學研究和診斷領(lǐng)域非常流行的分子標記物。這些熒光素的發(fā)射光為紅光,在這個范圍大多數(shù)CCD檢測器具有zui大檢測靈敏度,而且是生物物質(zhì)低背景區(qū)。染料的顏色是非常強烈的,因此在凝膠電泳中低至1nmol的量都能被肉眼觀測到。CY5 NHS ester是用于標記多肽、蛋白和寡核苷酸的氨基基團的活性染料。在標記反應中該染料需要少量的有機共溶劑(如DMF,DMSO)(請參照我們的推薦手冊以獲得更多幫助信息)。對于可溶性蛋白、各種各樣的多肽和寡核苷酸而言,這種染料是非常理想而且成本低廉的。該染料在有機溶劑對小分子物質(zhì)的標記也是非常有效的。對于更多的精細目標物,如易降解蛋白,如果DMF或DMSO會對其有影響,可以考慮water-soluble Cy5 NHS ester(水溶性Cy5 NHS ester染料),因為它們不需要有機溶劑助溶,而且具有和熒光染料類似的性質(zhì)。
CY5熒光團可以與很多的儀器如熒光顯微鏡、成像儀、掃描儀、熒光分析儀等相兼容。許多的CY5衍生物——CY5 NHS ester可以替代Alexa Fluor 647和 DyLight 649等活化酯(activated esters)。
