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.
