Texas Red

Texas Red (Sulforhodamine 101 acid chloride) is an orange/red emitting dye with an excitation peak at 596 nm and an emission peak at 615 nm. Alternatives to Texas Red that can offer increased photostability and brightness include Alexa Fluor™ 594 (ThermoFisher Scientific), DyLight™ 594 (ThermoFisher Scientific), or CF®594 (BD Biosciences). Texas Red is most commonly used in cellular fluorescence microscopy applications, as the 594 nm laser is rare in flow cytometry. However, it can be sub-optimally excited by the 561 nm yellow-green laser. Texas Red is commonly used as an acceptor in the tandem fluorophore, PE-Texas Red also called ECD. see less Texas Red (Sulforhodamine 101 acid chloride) is an orange/red emitting dye with an excitation peak at 596 nm and an emission peak at 615 nm.
