Thermo Scientific™ DyLight™ 550 Maleimide
Thermo Scientific DyLight 550 Sulfhydryl-Reactive Dye is a maleimide-activated derivative of high-performance DyLight 550 used to fluorescently label sulfhydryl-containing peptides, proteins and other biomolecular probes.
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 over a broad pH range (pH 4-9). The high water solubility of DyLight Fluors means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates.
Features
- High performance—DyLight 550 shows brighter fluorescence than Alexa Fluor 555, TRITC and Cy3 dye
- Specific—maleimide-activated dye labels proteins and other molecules at reduced sulfhydryls (-SH)
- Efficient labeling methods—well-characterized chemistry and optimized protocols provide for reliable, high-quality labeling
- Optimized antibody labeling procedure—complete protocol for IgG reduction and labeling and calculating the labeling efficiency
