Alexa Fluor® and BODIPY® Fluorescent Dyes Make Excellent Probes
Probes made with labeled nucleotides can be used for multicolor techniques such as in situ hybridization and hybridization to arrays. Our proprietary BODIPY® and Alexa Fluor® dye conjugates are exceptionally bright, photostable, and essentially pH insensitive. The narrow emission profile of the BODIPY® dyes helps ensure minimal spectral overlap. The Alexa Fluor® dyes are highly water soluble, as are DNA probes made from them, making them the labels of choice for fluorescence in situ hybridization.

Long Linkers Improve Performance
The ChromaTide® dUTP and UTP nucleotides are modified at the C-5 position of uridine via a unique alkynylamino linker, which provides a spacer between the nucleotide and the dye to reduce interactions between them. The number in the product name, e.g., the “12” in fluorescein-12-dUTP, indicates the net length of the spacer, in atoms. These spacers result in brighter conjugates and increased hapten accessibility for secondary detection reagents.

Fluorescein-aha-dUTP - 1 mM in TE Buffer (Invitrogen™)

Labeled 5-aminohexylacrylamido-dUTP (aha-dUTP) nucleotides are modified at the C-5 position of uridine with a unique hexylacrylamide linker, which serves as a spacer between the nucleotide and the dye. This spacer reduces interactions between the nucleotide and the dye, resulting in brighter conjugates and increased hapten accessibility for secondary detection reagents. Labeled nucleotides can be used to generate labeled nucleic acid hybridization probes for many molecular biology and molecular cytogenetics applications, including multicolor techniques.

MANT-ATP (2'-(or-3')-O-(N-Methylanthraniloyl) Adenosine 5'-Triphosphate, Trisodium Salt) (Invitrogen™)

The nucleotide analog MANT ATP is modified on the ribose moiety. The compact mature of the MANT fluorophore and its attachment position results in nucleotide analogs that induce minimal perturbation of nucleotide-protein interactions. Because MANT fluorescence is sensitive to the environment of the fluorophore, nucleotide-protein interactions may be directly detectable. MANT nucleotides are valuable probes of the structure and enzymatic activity of nucleotide-binding proteins.

TNP-ATP (2'-(or-3')-O-(Trinitrophenyl) Adenosine 5'-Triphosphate, Trisodium Salt) (Invitrogen™)

The nucleotide analog TNP-ATP is modified on the ribose moiety and is essentially non-fluorescent in water. The TNP nucleotides undergo an equilibrium transition to a semiquinoid structure that has relatively long-wavelength spectral properties; this form is only fluorescent when bound to the nucleotide-binding site of some proteins.

Alexa Fluor™ 647 ATP (Adenosine 5'-Triphosphate, Alexa Fluor™ 647 2'-(or-3')-O-(N-(2-Aminoethyl) Urethane), Hexa(Triethylammonium) Salt) (Invitrogen™)

Alexa Fluor® 647 adenosine 5´triphosphate (Alexa Fluor® 647 ATP) is a mixed-isomer comprised of the Alexa Fluor® 647 fluorophore, an exceptionally bright far-red fluorescent dye attached to the 2´ or 3´ position of the ribose ring via an aminoethylcarbamoyl linker.

BODIPY™ FL ATP-γ-S, Thioester (Adenosine 5'-O-(3-Thiotriphosphate), BODIPY™ FL Thioester, Sodium Salt) (Invitrogen™)

BODIPY® FL ATP-γ-S binds to ATP-binding proteins. To create this fluorescent nucleotide, the BODIPY FL fluorophore was linked through the γ-thiol of ATP-γ-S. In addition to its potential use for binding studies, the BODIPY FL ATP-γ-S thioether is an important new substrate for Fhit, a member of the histidine triad superfamily of nucleotide-binding proteins.

MANT-GDP (2'-(or-3')-O-(N-Methylanthraniloyl) Guanosine 5'-Diphosphate, Disodium Salt) (Invitrogen™)

The nucleotide analog MANT GDP is modified on the ribose moiety. The compact mature of the MANT fluorophore and its attachment position results in nucleotide analogs that induce minimal perturbation of nucleotide-protein interactions. Because MANT fluorescence is sensitive to the environment of the fluorophore, nucleotide-protein interactions may be directly detectable. MANT nucleotides are valuable probes of the structure and enzymatic activity of nucleotide-binding proteins.

BODIPY™ FL ATP (Adenosine 5´-Triphosphate, BODIPY™ FL 2´-(or-3´)-O-(N-(2-Aminoethyl)Urethane), Trisodium Salt), 5 mM in buffer (Invitrogen™)

BODIPY FL adenosine 5'-triphosphate and BODIPY FL guanosine 5'-triphosphate (G-12411) are composed of a BODIPY FL fluorophore attached to the 2' or 3' position of the ribose ring via a linker. Interactions between the fluorophore and the purine base are evident from the spectroscopic properties of these nucleotide analogs. The fluorescence quantum yield of BODIPY FL GTP is only about one-tenth that of BODIPY FL ATP; however, this yield may be enhanced upon binding of BODIPY FL GTP to GTP-binding proteins.
