| 20080206872 | Nucleic acid integration in eukaryotes - The invention relates to methods for directing integration of a nucleic acid of interest towards homologous recombination and uses thereof. The present invention discloses factors involved in integration of a nucleic acid by illegitimate recombination which provides a method of directing integration of a nucleic acid of interest to a predetermined site, whereby the nucleic acid has a homology at or around the predetermined site, in a eukaryote with a preference for non-homologous recombination comprising steering an integration pathway towards homologous recombination. Furthermore, the invention provides a method of directing integration of a nucleic acid of interest to a subtelomeric and/or telomeric region in a eukaryote with a preference for non-homologous recombination. | 08-28-2008 |
| 20090064377 | METHOD AND MEANS FOR TARGETED NUCLEOTIDE EXCHANGE - The invention pertains to a method for targeted alteration of a duplex acceptor DNA sequence, comprising combining the duplex acceptor DNA sequence with a donor oligonucleotide, wherein the duplex acceptor DNA sequence contains a first DNA sequence and a second DNA sequence which is the complement of the first DNA sequence and wherein the donor oligonucleotide comprises a domain that comprises at least one mismatch with respect to the duplex acceptor DNA sequence to be altered, preferably with respect to the first DNA sequence, and wherein a section of the donor oligonucleotide is methylated to a higher degree than the second DNA sequence and/or wherein the second DNA is methylated to a lower degree than the corresponding section of the donor oligonucleotide, optionally in the presence of proteins that are capable of targeted nucleotide exchange and to oligonucleotides for use in the method. | 03-05-2009 |
| 20090307805 | ALTERNATIVE NUCLEOTIDES FOR IMPROVED TARGETED NUCLEOTIDE EXCHANGE - A method and oligonucleotides for targeted nucleotide exchange of a duplex DNA sequence, wherein the donor oligonucleotide contains at least one modified nucleotide having a higher binding affinity compared to naturally occurring A, C, T or G and/or binds stronger to a nucleotide in an opposite position in the first DNA sequence as compared to a naturally occurring nucleotide complementary to the nucleotide in the opposite position in the first DNA sequence. | 12-10-2009 |
| 20100055780 | TARGETED NUCLEOTIDE EXCHANGE WITH PROPYNYL MODIFIED OLIGONUCLEOTIDES - A method and oligonucleotides for targeted nucleotide exchange of a duplex DNA sequence, wherein the donor oligonucleotide contains at least one modified nucleotide which is a propynylated purine and/or pyrimidine having a higher binding affinity compared to naturally occurring A, C, T or G and/or binds stronger to a nucleotide in an opposite position in the first DNA sequence as compared to a naturally occurring nucleotide complementary to the nucleotide in the opposite position in the first DNA sequence. | 03-04-2010 |
| 20100186124 | TARGETED NUCLEOTIDE EXCHANGE WITH LNA MODIFIED OLIGONUCLEOTIDES - A method and oligonucleotides for targeted nucleotide exchange of a duplex DNA sequence, wherein the donor oligonucleotide contains at least one modified nucleotide which is a LNA having a higher binding affinity compared to naturally occurring A, C, T or G and/or binds stronger to a nucleotide in an opposite position in the first DNA sequence as compared to a naturally occurring nucleotide complementary to the nucleotide in the opposite position in the first DNA sequence. | 07-22-2010 |
| 20100223691 | TARGETED NUCLEOTIDE EXCHANGE WITH IMPROVED MODIFIED OLIGONUCLEOTIDES - A method and oligonucleotides for targeted nucleotide exchange of a duplex DNA sequence, wherein the donor oligonucleotide contains at least two modified nucleotides, at least one of which is a propynylated purine and/or pyrimidine and at least one of which is a LNA having a higher binding affinity compared to naturally occurring A, C, T or G and/or binds stronger to a nucleotide in an opposite position in the first DNA sequence as compared to a naturally occurring nucleotide complementary to the nucleotide in the opposite position in the first DNA sequence. | 09-02-2010 |
| 20100291684 | MUTAGENESIS METHOD USING POLYETHYLENE GLYCOL MEDIATED INTRODUCTION OF MUTAGENIC NUCLEOBASES INTO PLANT PROTOPLASTS - Method for targeted alteration of a duplex acceptor DNA sequence in a plant cell protoplast, comprising combining the duplex acceptor DNA sequence with a donor mutagenic nucleobase, wherein the duplex acceptor DNA sequence contains a first DNA sequence and a second DNA sequence which is the complement of the first DNA sequence and wherein the donor mutagenic nucleobase comprises at least one mismatch with respect to the duplex acceptor DNA sequence to be altered, preferably with respect to the first DNA sequence, wherein the method further comprises a step of introducing the donor mutagenic nucleobase into the cell protoplasts using polyethylene glycol (PEG) mediated transformation and the use of PEG protoplast transformation for enhancing the rate of targeted mutagenesis. | 11-18-2010 |
