Other Labeling Dyes

BioActs provides other traditionally used dyes such as 5(6)-Carboxyfluorescein (FAM) and 5(6)-Carboxytetramethylrhodamine (TAMRA) dyes for labeling of biomolecules. FAM is one of popular green fluorescent reagents used for labeling peptides, proteins and nucleotides. In addition to relatively high absorptivity, good fluorescence quantum yield and good water solubility, FAM has an excitation maximum that closely matches the 488 nm spectral line of the argon-ion laser. TAMRA fluorophore has been a widely used for preparing bioconjugates, especially fluorescent antibody and avidin derivatives. TAMRA dye is also widely utilized for oligonucleotide labeling and automated DNA sequencing applications. TAMRA is often used as FRET acceptor for FAM fluorophore.

-    Other fluorescent dyes such as Cyanine, ICG, TAMRA, FAM, etc. are also available.

-    ​All dyes are equipped with various reactive and functional groups.

- ​   High quality and excellent performance
