Description Molecular Probes is pleased to offer the ATTO-TAG series of reagents for the ultrasensitive detection of primary amines. Developed by Novotny and collaborators at Indiana University, the ATTO-TAG reagents are similar to the important reagents o-phthaldialdehyde (OPA), naphthalene-2,3-dicarboxaldehyde (NDA) and anthracene-2,3-dicarboxaldehyde, all of which are also available in high purity form from Molecular Probes.

Principle:
ATTO-TAG CBQCA (3-(4-carboxybenzoyl)quinoline-2-carboxaldehyde or CBQCA 1) and ATTO-TAG FQ (3-(2-furoyl) quinoline-2-carboxaldehyde 2) react specifically with primary amines to form conjugates that can be analyzed by electrophoretic or chromatographic methods. Unlike OPA and NDA, ATTO-TAG CBQCA will also react with hydrophilic peptides and amino sugars. The resulting products of CBQCA highly fluorescent 7-aza-1-cyano-5,6-benzisoindoles are maximally excited at 450nm or by the 442 nm spectral line of the He-Cd laser and have emission maxima at ~550 nm. The products of ATTO-TAG FQ are maximally excited at 480 nm or by the 488 nm line of the argon-ion laser and have emission maxima at ~590 nm. In capillary zone electrophoresis (CZE), the sensitivity of detection of ATTO-TAG CBQCA conjugates should be in the attomole range (10-18 moles). The high sensitivity, freedom from background and long-wavelength excitability make these potential reagents for research, diagnostic and forensic applications, including drug analysis. The ATTO-TAG reagents can, of course, be used in HPLC and other modes of chromatography with either absorbance or fluorescence detection. The principal limitation to obtaining ultrasensitive detection using chemical derivatization reagents, including the ATTO-TAG reagents, is that relatively high concentrations of the derivatizing reagent are required to obtain adequate kinetics and sufficient modification of the analyte. A recently described technique employs ATTOTAG FQ for the solid-phase derivatization of dilute solutions (10-8 M) of peptides that have been immobilized on Immobilon-CD membranes. This method permits the quantitative derivatization and analysis by capillary electrophoresis of only a few picomoles of the analyte.
