(TF2) family has the spectral properties similar to those of fluoresceins and Alexa Fluor? 488 (Alexa Fluor? is the trademark of Invitrogen). Compared to fluoresceins TF2 family has much stronger fluorescence and higher photostability. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to fluoresceins. TF2-labeled peptides and nucleotides exhibit much stronger fluorescence and higher photostability than the ones labeled with FITC or FAM. In addition, TF2 has spectral properties, pH dependence and photostability similar to Alexa Fluor? 488, making them excellent replacement for the expensive Alexa Fluor? 488.

Product Legend
Fluorescent dye NHS esters (or succinimidyl esters) are the most popular tool for conjugating dyes to a peptide, protein, antibody, amino-modified oligonucleotide or nucleic acid. NHS esters react readily with the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting dye conjugates are quite stable.
