Background
Flamma® Fluors
BioActs offers a broad range of Flamma® Fluors dyes equipped with variety of reactive and functional groups, which can cover the full spectral range from UV to NIR with their excellent fluorescence performance. Characteristic features of these superior dyes are strong absorption, high fluorescence quantum yield and high photostability. Flamma® dyes maintain good fluorescence activity and stability after conjugation to biomolecules and allow the detection of low-abundance biological structures with great sensitivity. The dyes are compatible with optical conditions of most of fluorescent equipment and are ideal for any applications in biological studies.
- Covering the full spectral range from UV to NIR
- Equipped with a variety of reactive groups: NHS and Sulfo-NHS ester, Vinylsulfone, Maleimide, Click chemistry, isothiocyanate, hydrazide and hydrophobic substances.
- High quantum yields and photostability
- High purity and compatible with most of biomolecules
Flamma® Fluors Dichlorotrazine
Flamma® Fluors dichlorotriazine is for labeling hydroxyl groups. Hydroxyls irreversibly displace one of chlorine at triazine ring via SNAr reaction pathway to yield an aryl ether linkage. Dichlorotriazines are among the few reactive groups that are reported to react directly with polysaccharides and other alcohols in aqueous solution, provided that the pH is >9 and other nucleophiles are not present.
