在过去的几年里,CY5荧光团已经成为生命科学研究和诊断领域非常流行的分子标记物。这些荧光素的最强发射光为红光,在这个范围大多数CCD检测器具有最大检测灵敏度,而且是生物物质低背景区。染料的颜色是非常强烈的,因此在凝胶电泳中低至1nmol的量都能被肉眼观测到。CY5 NHS ester是用于标记多肽、蛋白和寡核苷酸的氨基基团的活性染料。在标记反应中该染料需要少量的有机共溶剂(如DMF,DMSO)(请参照我们的推荐手册以获得更多帮助信息)。对于可溶性蛋白、各种各样的多肽和寡核苷酸而言,这种染料是非常理想而且成本低廉的。该染料在有机溶剂对小分子物质的标记也是非常有效的。对于更多的精细目标物,如易降解蛋白,如果DMF或DMSO会对其有影响,可以考虑water-soluble Cy5 NHS ester(水溶性Cy5 NHS ester染料),因为它们不需要有机溶剂助溶,而且具有和荧光染料类似的性质。
CY5荧光团可以与很多的仪器如荧光显微镜、成像仪、扫描仪、荧光分析仪等相兼容。许多的CY5衍生物——CY5 NHS ester可以替代Alexa Fluor 647和 DyLight 649等活化酯(activated esters)。
