CY3荧光染料激发光和CY3发射光是多少？

CY3荧光染料用哪个波段激发？

经常有同学咨询，CY3荧光染料用哪个波长激发，发出来的是什么颜色的光，现将厂家的说明提供如下：

Invitrogen Cy3 dye is a bright, orange-fluorescent dye that can be excited using the 532 nm laser line and visualized with TRITC (tetramethylrhodamine) filter sets. In addition to immunocytochemistry applications, Cy3 dye is commonly used to label nucleic acids.

The Cy3 fluorophore is also the basis for the lipophilic neuronal and long-term DiI cell tracing reagents, which append alkyl tails (≥12 carbons) onto the core fluorophore. The Cy3 dye is a traditional orange-fluorescent label for protein and nucleic acid conjugates used for imaging, flow cytometry, and genomic applications. It is also the basis for the classic lipophilic tracer DiI and its variants.

从上面资料可以看到，CY3荧光染料用532nm波段激发（绿光），发出来的是橙色光。
