About Alexa Fluor 568

---

Alexa Fluor™ 568 (AF568, Alexa 568) has an excitation peak at 578 nm and an emission peak at 603 nm, and is spectrally similar to Rhodamine B. Alexa 568 is commonly used fluorescence and super-resolution microscopy. Many flow cytometers are equipped with 561nm lasers, so while Alexa 568 can be used for flow cytometry, PE or NovaFluor Yellow 570 are more commonly used due to their brightness and spectral characteristics.
