5'-Biotin CE Phosphoramidite - CAS 135137-87-0

5'-Biotin CE Phosphoramidite - CAS 135137-87-0 Catalog number: BRI-004

5'-Biotin Phosphoramidite for direct labeling of synthetic oligonucleotides has the following characteristics:

  • Soluble in acetonitrile at concentrations useful for DNA synthesis.
  • Include the DMT group used for cassette purification, which is essential for the preparation of biotinylated PCR primers because cross-contamination may occur during HPLC purification.
  • To develop diagnostic probes, biotin phosphoramidite can be branched to allow the introduction of multiple biotins at the 3'or 5'end.

* Please kindly note that our products are not to be used for therapeutic purposes and cannot be sold to patients.
