On demandThermo Scientific™ DyLight™ 550 NHS Ester, 5 x 50 µg
Thermo Scientific DyLight 550 Amine-Reactive Dye is an NHS ester-activated derivative of high-performance DyLight 550 used to fluorescently label antibodies and other proteins that are then used as molecular probes for cellular imaging and other fluorescence detection methods.
DyLight 550 provides vibrant orange-to-red fluorescence with better performance than other rhodamine derivatives, including Alexa Fluor™ 555, TRITC, and Cy3™ dye for fluorescent applications. The high water solubility of DyLight Fluors means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates. DyLight 550 Amine-Reactive Dye is also available as part of two antibody labeling kit sizes.
Features
- High performance—DyLight 550 shows brighter fluorescence than Alexa Fluor 555, TRITC, and Cy3 dye
- Specific—NHS ester-activated dye labels proteins and other molecules at primary amines (-NH2)
- Optimized procedure—following the standard protocol results in antibodies with excellent dye:protein ratios and recovery rates for optimum activity and fluorescence labeling
