ReadiLink™ Cy5 Nick Translation dsDNA Labelling Kit provides a simple and efficient way to label a double stranded DNA sample with the bright and photostable Cy5 dye. 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 Cy5 dye is conjugated. In addition, the kit allows the user to optimize incorporation and product size by adjusting the ratio of Cy5-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 Cy5-labeled DNAs can be used in a variety of molecular biology techniques such as fluorescence in situ hybridization (FISH).

Protocol summary

Prepare DNA samples
Add reagents to tube
Mix and centrifuge briefly
Incubate at 15 °C for 60 minutes
Place the reaction on ice followed by addition of Stop Solution and heating at 65 °C
Place on ice for 5 minutes before using or store at 4 °C
Purify the labelled DNA

Important

Thaw all the kit components on ice before starting the experiment. Briefly vortex all the reagents to the bottom before starting the labelling process.

SAMPLE EXPERIMENTAL PROTOCOL

The following protocol can be used as a guideline.
Table 1.Reagents composition per tube for each reaction

Components	Amount
DNA sample	1 µg DNA diluted in Nuclease-free water to final volume of 34 µL
Nick Translation Buffer	5 µL
dNTP mix	5 µL
dTTP	2 µL
Cy5-dUTP working solution	2 µL
DNA Polymerase I	1 µL
DNase I	1 µL
Total Volume	50 µL

The ratio of Cy5-dUTP (Component A): dTTP (Component E) can be optimized to achieve the best labelling conditions.
Incubation time can be optimized for better labelling. Longer incubation time will help with more labelling but may shorten the size of the end product.

To a clean (Nuclease-free) 0.5 mL micro centrifuge tube or 0.2 mL PCR tube, add the reagents in the order indicated in Table 1.
Carefully mix the reagents by a brief vortex followed by brief centrifuge.
Incubate the reaction at 15 °C for 60 minutes.
After incubation, place the reaction on ice.
To terminate the reaction, add 5 µL of Stop Solution and heat the sample at 65 °C.
Place on ice for 5 minutes before using or store at 4 °C.
Purify the labeled DNA.
