Thermo Scientific North2South Random Prime DNA Biotinylation Kit uses random heptanucleotides, Klenow fragment and biotin-nucleotides to produce biotinylated DNA templates for DNA hybridization and detection methods.
- Works with as little as 100ng starting DNA template
- Exonuclease-free Klenow fragment in the DNA labeling kit produces higher yields
- Each reaction yields probe sufficient for approximately three (10 x 10cm) blots
This random prime DNA labeling kit is based on the procedure of Feinberg and Vogelstein (Ref.4,5). Random heptanucleotides containing all possible sequences are annealed to a denatured DNA template. These act as primers for complementary strand synthesis by DNA Polymerase (Klenow fragment, 3'-5' exo-). Biotinylated dNTPs in the reaction mix are incorporated into the newly synthesized DNA. This protocol yields biotin-labeled DNA of high activity for use as probes in hybridization experiments such as Southern and Northern hybridizations. The resulting hybrids can be detected with streptavidin-horseradish peroxidase (HRP) and a chemiluminescent substrate kit such as North2South Chemiluminescent Hybridization and Detection Kit.
