Thermo Fisher, C7631, ChromaTide™ Texas Red™-12-dUTP

Thermo Fisher, C7631, ChromaTide™ Texas Red™-12-dUTP Molecular Probes™ ChromaTide™ dye labeled dUTP, OBEA-dCTP, and UTP nucleotides can be used to synthesize labeled DNA probes without the need for hazardous and expensive radioisotope-labeled nucleotides. These nucleotides can be incorporated using standard molecular biology techniques; labeled probes can then be used inin situhybridization, microarray, or blotting protocols. ChromaTide™ dye labeled nucleotides are available in different fluorescent colors to facilitate multicolor analysis.

Alexa Fluor™ and BODIPY™ Fluorescent Dyes Make Excellent ProbesProbes made with labeled nucleotides can be used for multicolor techniques such asin situhybridization 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 fluorescencein situhybridization.
Long Linkers Improve PerformanceThe 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.
