  • Publication number: 20220220545
    Abstract: Described herein are compositions and methods for the production and quantification of barcoded or unique molecular identifier (UMI)-labeled substrates. In one aspect, the substrate is a bead comprising a template oligonucleotide that is elongated by successive extension reactions to provide a bead with an oligonucleotide comprising a plurality of barcodes and conserved anchor regions. Methods are also described for quantifying the amount of template oligonucleotide loaded onto the substrate and the products of the extension reaction after each round and after the final extension.

  • Patent number: 10233450
    Abstract: 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.

  • Patent number: 9988630
    Abstract: 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.
