ReadiLink™ Biotin Nick Translation dsDNA Labeling Kit

ReadiLink™ Biotin Nick Translation dsDNA Labelling Kit provides a simple and efficient way to label a double stranded DNA sample with Biotin tag. The labelling kit provides all necessary reagents for a complete workflow required for DNA labelling. This method utilizes a combination of DNAse and DNA polymerase to nick one strand of the DNA helix, to which Biotin is conjugated. In addition, the kit allows the user to optimize incorporation and product size by adjusting the ratio of Biotin-dUTP conjugate to dTTP. It is compatible with a wide variety of sample materials, including bacterial artificial chromosome (BAC) DNA, human genomic DNA, purified PCR products, supercoiled and linearized plasmid DNA. The resulted Biotin-labeled DNAs can be used in a variety of molecular biology techniques such as fluorescence in situ hybridization (FISH).

Nick translation labeling of DNA starts with the creation of defects within the sequence of existing DNA double-helix molecules by cleavage of phosphodiester bonds with DNase along the backbone of one strand. Polymerase then repairs these nicks beginning with the removal of the adjacent nucleotide and the immediate filling back in of those gaps with new nucleotides from the added dNTP pool. As each new nucleotide is added, the polymerase leaves the 3′ OH group open, thus translating the nick toward the 5′ end. As the reaction sequence is repeated, the polymerase enzyme continues to remove existing nucleotides and replace them with new ones at the site of the new nick. The result of these reactions is numerous labeled and unlabeled nucleotides being incorporated as a complementary sequence along the length of each DNA strand, starting at the site of the original nick.
