ReadiLink™ DIG (Digoxigenin) Oligo and ssDNA Labeling Kit
ReadiLink™ DIG (Digoxigenin) Oligo and ssDNA Labelling Kit enables simple and uniform tagging of single-stranded DNA or oligos with DIG tag. The labelling kit uses our proprietary TAQuest™ terminal deoxynucleotidyl transferase (TdT) to catalyze non-template directed nucleotide incorporation onto the 3’- end of single-stranded DNAs or oligos. The kit is optimized for efficient labelling and contains all the essential reagents required for efficient labelling of ssDNA or oligos. The resulting DIG-labeled oligo and ssDNA probes are ideally suited for a variety of biological applications, e.g., electrophoretic mobility shift assays (EMSA), Northern and Southern blots, colony or in situ hybridizations.
Example protocol
AT A GLANCE
Protocol summary
- Prepare oligo or ssDNA samples
- Add reagents to tube
- Mix and centrifuge briefly
- Incubate at 37 °C for 60 minutes
- Place on ice for 5 minutes
- Purify the labeled DNA
Note: Thaw all the kit components on ice before starting the experiment. Briefly centrifuge all the reagents to the bottom before starting the labeling process.
SAMPLE EXPERIMENTAL PROTOCOL
The following protocol can be used as a guideline.
Note: The amount of DIG-dUTP can be optimized to achieve the best labeling conditions.
- To a clean (Nuclease-free) 0.5 mL microcentrifuge tube or 0.2 mL PCR tube, prepare a reaction mix by adding the reagents in the order indicated in Table 1.
- Carefully mix the reagents by a brief vortex, followed by a brief centrifuge.
- Incubate the reaction at 37 °C for 60 minutes.
- After incubation, place the reaction on ice for 5 minutes.
- Purify the labeled DNA.
