Overview SDS Protocol

ReadiLink™ Biotin Oligo and ssDNA Labelling Kit enables simple and uniform tagging of single-stranded DNA or oligos with biotin 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 biotinylated 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.

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.

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.

Table 1.Reagents composition per tube for each reaction

Components	Amount
Oligo or ssDNA sample	1 µg DNA diluted in Nuclease-free water to a final volume of 5 µL
TdT Reaction Buffer	40 µL
Biotin-dUTP	1-2 µL
