DNA/cDNA Labeling

Fluorophores and haptens, are the most commonly used labels for the generation of non-radioactive DNA/cDNA probes. They are enzymatically introduced into DNA/cDNA via modified nucleotides that are incorporated as substitutes for their natural counterparts in either a one-step procedure (introduction of a fluorescent or hapten-modified nucleotide) or a two-step procedure (introduction of a reactive group carrying nucleotide and subsequent fluorescent or hapten labeling).

Fluorescent Nick Translation Labeling Kits

Nick translation is the method of choice for the generation of labeled DNA probes (100- 500 bp) from large templates such as genomic DNA, cosmids, BAC clones. It is based on the concerted activities of DNAse I (introduction of random single-strand breaks (“nicks”) into double-stranded DNA) and Polymerase I that incorporates labeled dUTPs instead of their natural counterpart dTTP at the “nicked” sites thus creating ideal in situ hybridization probes. There is no net DNA synthesis in contrast to PCR-based labeling approaches.

Biotin & Digoxigenin Nick Translation Labeling Kits are available as well.

Biotin & Digoxigenin 3' End Oligonucleotide Labeling Kits

3’-End labeled oligonucleotides can be used as sequence-specific protein binding or nucleic acid hybridization probes e.g. for EMSA, Northern or Southern blots. Compared to internal, random labeled probes, the label is located at the 3‘-End only and less likely interferes with probe binding.

The combination of (poly)-HRP-conjugated Biotin/Digoxigenin detection reagents with AzDye488 -, AzDye546- or AzDye594 -labeled tyramide further increases detection sensitivity of up to 100-fold.

Figure 1 Terminal deoxynucleotidyl Transferase (TdT) template-independently transfers labeled nucleotides to the 3’-OH group of ssDNA/oligonucleotides. The number of nucleotide and thus label incorporation depends on the type of nucleotide ((dd)UTP) and type of label (n = 1 for labeled ddUTP, n = 1 – 3 (average) for labeled UTP, n > 1 for labeled dUTP (multiple label, tail length is highly nucleotide specific).
