Medchemexpress LLC Cy3-PEG2-endo-BCN bromide | >98.0% | 843.93 Da | C47H63BrN4O5 | 10 MG
Supplier: Medchemexpress LLC HY155327B10MG
Cy3-PEG2-endo-BCN bromide is a Cyanine 3-derived fluorescent reagent with a PEG2 linker and an endo-BCN reactive moiety, supplied as the bromide salt. It is optimized for catalyst-free strain-promoted alkyne-azide cycloaddition (SPAAC) to label azide-bearing biomolecules for fluorescence imaging, biochemical assays, and probe synthesis.
- Enables catalyst-free SPAAC click chemistry with azide-functionalized molecules.
- PEG2 linker improves solubility and reduces steric hindrance in conjugation.
- Bromide salt form simplifies handling and storage.
- Strong orange-red fluorescence suitable for imaging and detection.
- Ideal for preparing fluorescent bioconjugates and probes.
