Tetrafluorophenyl (TFP) esters are an improvement over the succinimidyl ester (SE or NHS-ester) chemistry typically used to attach fluorophores or haptens to the primary amines of biomolecules. Both reactive chemistries produce the same strong amide bond between the dye or hapten and the compound of interest, but TFP esters are less susceptible to spontaneous hydrolysis during conjugation reactions. Alexa Fluor TFP esters are stable for several hours at the basic pH typically used for reactions – far outlasting succinimidyl esters.

This single 5-isomer preparation of our proprietary, amine-reactive dye, Oregon Green 488 carboxylic acid, succinimidyl ester and its conjugates have green fluorescence similar to that of fluorescein but are more photostable. Additionally, Oregon Green 488 dye has a lower pK a than fluorescein (pK a = 4.7 versus 6.4 for fluorescein), making this bright dye less pH sensitive in the physiological range.

Pacific Green™ Succinimidyl Ester is a violet-excitable (411 nm) dye with an emission maximum at ~500 nm, allowing it to be used with other violet-excitable fluorophores (such as Pacific Blue™ or Pacific Orange™ dye) for multiparameter analysis using a single excitation source. As a class of compounds, succinimidyl esters offer an efficient and easy-to-use means for selectively linking a dye to accessible primary amine groups on proteins, modified nucleic acids, or other biomolecules. The covalent bonds formed are as stable as the peptide bonds used to link the amino acids within proteins. Pac...
