1. A method for regenerating a 3′
- hydroxyl group, the method comprising;
using a mixture comprising at least one reversibly modified oligonucleotide having a non-hydroxyl group 3′
end which can be converted into a 3′
hydroxyl group, wherein the oligonucleotide has a carboxylic acid ester group at its 3′
end;
exposing the mixture to a first chemical and a first range of temperature, wherein the first chemical and the first range of temperatures regenerate the 3′
hydroxyl group, wherein the first chemical is an amine;
wherein the amine is selected from the group consisting of methylamine, ethylenediamine, and triethylamine, andregenerating the 3′
hydroxyl group of the at least one reversibly modified oligonucleotide having a non-hydroxyl 3′
end.

Abstract
The present invention provides a method for amplification of a target nucleic acid sequence or signal, wherein an amplification reaction mixture is used which contains at least one reversibly modified oligonucleotide having a non-hydroxyl group 3′ end which can be converted into a hydroxyl 3′ end upon exposure to a chemical and/or irradiation and/or a range of temperature. The present invention also provides a reversibly modified oligonucleotide as described above, and a nucleic acid amplification reaction mixture and kit comprising such an oligonucleotide.
