Method for isolating and recovering target DNA or RNA molecules having a desired nucleotide sequence
First Claim
1. A method for denaturing or separating double-stranded nucleic acid molecules, said method comprising contacting one or more double-stranded nucleic acid molecules with a denaturant selected from the group consisting of(a) one or more amino acids comprising:
- glycine, α
-alanine, isoleucine, leucine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine or valine, (b) imidazole, and (c) one or more amino acid denaturants plus imidazole, thereby forming single-stranded nucleic acid molecules.

Abstract
The invention generally concerns the use of amino acid denaturants for denaturing or separating double stranded nucleic acid molecules. More specifically, the present invention provides a method for the rapid isolation and recovery of a desired target DNA or RNA molecules from a mixture or library containing such molecules. The method involves the use of haptenylated probes and amino acid denaturants to select the desired molecules and eliminate the undesired library members from a sample. The invention also provides a method in which larger or full-length nucleic acid molecules can be isolated from the subpopulation of desired molecules.

10. A method of recovering one or more desired target nucleic acid molecules from a population of nucleic acid molecules comprising:
-
(a) contacting said population with one or more haptenylated probes to permit said probe to hybridize to said desired target molecules thereby forming one or more hybridized molecules; and
(b) isolating said desired target nucleic acid molecules from said probes by contacting said hybridized molecules with a denaturant selected from the group consisting of (i) one or more amino acids comprising;
glycine, a-alanine, isoleucine, leucine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine or valine,(ii) imidazole, and (iii) one or more amino acid denaturants plus imidazole. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
