5(6)-Carboxyrhodamine 110 PEG3 Azide CAS:1582794-10-2 is a fluorescent labeling reagent that contains a carboxyrhodamine 110 (R110) dye, a PEG3 linker, and an azide group. The R110 dye is a bright and photostable fluorescent molecule that can be used for a range of applications, while the PEG3 linker provides a flexible spacer that can improve the sensitivity of the labeling reaction. The azide group can react specifically and efficiently with alkyne-functionalized molecules in a bioorthogonal “click” reaction, allowing for the site-specific labeling of a variety of molecules. This reagent is often used in bioconjugation reactions to attach the fluorescent R110 dye to biomolecules for imaging and detection purposes.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
