Add to Cart:
The Atto425 PCR Labeling Kit (10 reactions) provides a highly efficient, easy-to-perform and rapid labeling technology. All the reagents required for PCR labeling, with the exception of the primer, template, and materials for purification of the probe, are included. The kit is recommended for direct enzymatic labeling of DNA. The Atto425 PCR labeling mix contains specially optimized Atto425-dUTP for incorporation into DNA by PCR using Taq polymerase. In PCR labeling, repeated cycles of denaturation, annealing and extension allow the amplification of a specific DNA fragment. When dTTP is partially substituted by dye-dUTP, the extension of the annealed primers with Taq polymerase generates fluorescent labeled double-stranded DNA. The resultant DNA is suited for a variety of hybridization experiments, including Southern and Northern blots, colony hybridizations and in situ hybridizations.
