Biotinylated nucleotides are convenient tools for enzymatic labeling of DNA, RNA, and oligonucleotides with a biotin moiety. Double-stranded biotinylated probes are commonly produced by nick translation, random priming and PCR, while single-stranded probes are made by run-off polymerization, asymmetric PCR and primer extension.
The resulting biotin-labeled probes are applied in various techniques including Southern blots, Northern blots, dot blots or in situ hybridization.
The flexibility and length of the linker attaching the Biotin moiety may considerably influence nucleotide utilization. Jena Bioscience therefore, provides a diverse toolbox of biotinylated nucleotides with different linker lengths allowing to pick the perfect match for a particular application. Below is a selection of our biotinylated nucleotides analogs that have recently been referenced:
