Antibody-mediated detection and physical properties of oligonucleotides labelled with multiple internal and terminal 2,4-dinitrophenyl groups.

Abstract

DNP-labelled phosphoramidites have been used to synthesis oligonucleotides with multiple DNP reporter groups. The antibody-mediated detection and the stability of duplexes formed by these labelled oligonucleotides have been studied. A DNP-labelled deoxyuridine triphosphate has also been used to enzymatically incorporate DNP-labels into DNA via the polymerase chain reaction. The use of DNP-labelled primers in the PCR has also been investigated.
