About Alexa Fluor 546

---

Alexa Fluor™ 546 (AF546, Alexa 546) has an excitation peak at 556 nm and an emission peak at 573 nm, and is spectrally similar to Cy®3 (GE Healthcare), TRITC and iFluor® 555 (ATT Bioquest). Many flow cytometers are equipped with 532nm lasers, so while Alexa 546 can be used for flow cytometry, PE is more commonly used due to its brightness and spectral characteristics. This dye is commonly used for fluorescence microscopy applications.
