The Alexa Fluor 488 Oligonucleotide Amine Labeling Kit provides a simple method for labeling amine-modified oligonucleotides with our bright, photostable, green-fluorescent Alexa Fluor 488 dye (which is spectrally similar to fluorescein). Oligonucleotides labeled with this kit can be used as primers and as probes in hybridization experiments but should not be used for automated DNA sequencing since the Alexa Fluor dye in the kit is supplied as mixed isomers. The kits have been optimized for labeling reactions with 50 µg of a 5'-amine—modified oligonucleotide, 18 to 24 bases in length.

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.

Conjugates prepared with the thiol-reactive Alexa Fluor 647® C 2 maleimide are spectrally similar to the Cy5 dye, resulting in an optimal match to optical filters for the Cy5 dye. Total fluorescence of secondary antibody conjugates of Alexa Fluor® 647 dye, however, is significantly higher than that of Cy5 conjugates. Unlike the Cy5 dye, Alexa Fluor® 647 dye has very little change in absorption of fluorescence spectra when conjugated to most porteins, oligonucleotides, or nucleic acids, yielding greater total fluorescence at the same degree of substitution.
