top 2'-Deoxyinosine (2'-dI)

2´-Deoxyinosine (2´-dI) in an oligonucleotide is used for wobble positions, since it can form base pairs with all bases. As a specialty, we are able to introduce as many inosines as you require into one oligonucleotide! Several experiments have suggested that deoxyinosine might be an "inert" base; its presence in an oligonucleotide sequence seems neither to disturb DNA duplex formation nor to destabilize the duplex. Deoxyinosine containing primers have been used successfully to amplify cDNA or genomic fragments for the generation of DNA probes from a peptide sequence.

Features
  • 2´-dI can form base pairs with A, G, C and T*
  • useful when parts of your target sequence are unknown
  • great for targeting different mutants of a gene
  • 50% discount if more than 5 inosine modifications are requested in one order!
* the order of stabilities of base pairings is I-C >> I-A > I-T = I-G

top 2'-Deoxyuridine (2'-dU)

  • Replacement of thymidine with 2'-deoxyuridine results in destabilization of a DNA duplex
  • Is used in combination with Uracil-DNA glycosylase to avoid cross-contamination of PCR products
  • Useful for cloning of PCR-products (in combination with Uracil-DNA glycosylase)
