Cyanine 555 and Cyanine 647 alkynes can be used to analyze O-GlcNAcylated proteins by 2D glyco-DIGE (differential gel electrophoresis). They react with azide groups to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition. Cyanine 555 and Cyanine 647 are structurally identically to Cy®3 and Cy®5 dyes respectively from GE Healthcare.
- Size- and charge-matched for analysis of O-GlcNAcylated proteins via 2D glyco-DIGE.
- React with azides to form 1,2,3-triazole by copper(I) catalyzed 1,3-dipolar Huisgen cycloaddition.
- Structurally identical to Cy®3 and Cy®5 dyes.
Cyanine 555 (aka Cy®3):
-
- λEx/λEm (water) = 555/565 nm
- Dark red solid soluble in water, DMF and DMSO
- C40H56N4O7S2
- MW: 769
Cyanine 647 (aka Cy®5):
-
- λEx/λEm (water) = 650/665 nm
- Dark blue solid soluble in water, DMF and DMSO
- C42H58N4O7S2
- MW: 795

Laboratories、Sigma、Bio-Rad 及DAKO公司。 对于免疫荧光检测实验(包括免疫细胞化学及免疫组织化学),应用最广泛的是耦联有Alexa Fluor系列染料的抗体(如Alexa Fluor 488, 546, 568, 594, 596, 647, 633)、花青染料(Cyanine)系列标记的抗体(如Cy2, Cy3, and Cy5)、FITC及罗丹明(Rhodamine)。其中对于Alexa Fluor标记的二抗,推荐选择Invitrogen 公司
波长为520nm。由于FITC被使用了很长时间而且产量很大,FITC被广泛应用。荧光素的最大缺点是淬灭快,因此要和抗淬灭剂一起使用。DTAF是荧光素的一个衍生物,激发和发射波长均和FITC相同。当和链霉亲合素耦联时,因为荧光强度上有明显的区别,最好不使用FITC,而使用DTAF。 Cyanine dyes (Cy2, Cy3, Cy5) Cy2 耦联基团激发波长为492nm,发光为波长510nm的绿色
