2'-Deoxyinosine (dI) is the purine DNA nucleoside built from hypoxanthine and 2-deoxy-β-D-ribose. CH64006 is listed under CAS 890-38-0, molecular formula C10H12N4O4, molecular weight 252.23, and PubChem CID 135398593.

This record is distinct from inosine, the corresponding RNA nucleoside. Deoxyinosine is used as a universal-base residue in degenerate primer and probe design, and incorporated hypoxanthine provides an endonuclease V recognition site for nucleic-acid amplification decontamination studies.

应用背景

Degenerate primer and probe design: deoxyinosine pairs with all four canonical bases, and nearest-neighbor parameters are used in degenerate PCR-primer and microarray-probe design research.
Endonuclease V decontamination studies: incorporated hypoxanthine from dI is recognized by endonuclease V in carryover-amplicon cleavage methods.
dI nucleoside reference: CH64006 provides the deoxyinosine identity for nucleoside and oligonucleotide chemistry comparisons.

常见问题

Why is deoxyinosine called a universal base?

Deoxyinosine (dI) pairs with all four canonical bases (C, A, T, G) with relatively low discrimination, so it is used as a universal-base position in degenerate primers and probes.

How is deoxyinosine used in amplification decontamination?

When deoxyinosine is incorporated, the resulting hypoxanthine is the recognition site for endonuclease V, which cleaves carryover amplicons while leaving the intended template intact.
