Patent
Integrated Dna Technologies, Inc. | Date: 2016-10-21

This invention pertains to modified compositions for use in CRISPR systems, and their methods of use. In particular, length-modified and chemically-modified forms of crRNA and tracrRNA are described for use as a reconstituted guide RNA for interaction with Cas9 of CRISPR systems. The resultant length-modified and chemically-modified forms of crRNA and tracrRNA are economical to produce and can be tailored to have unique properties relevant to their biochemical and biological activity in the context of the CRISPR Cas9 endonuclease system.

The invention can be used to provide a more efficient and less error-prone method of detecting variants in DNA, such as SNPs and indels. The invention also provides a method for performing inexpensive multiplex assays.


Patent
City Of Hope and Integrated Dna Technologies, Inc. | Date: 2016-12-12

The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (dsRNA), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.

The invention provides compositions and methods for selectively reducing the expression of a gene product from a desired target gene, as well as treating diseases caused by expression of the gene. The method involves introducing into the environment of a cell an amount of a double-stranded RNA (dsRNA) such that a sufficient portion of the dsRNA can enter the cytoplasm of the cell to cause a reduction in the expression of the target gene. The dsRNA has a first oligonucleotide sequence that is between 26 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of from about 19 to about 23 nucleotides is complementary to a nucleotide sequence of the RNA produced from the target gene.
