  • Publication number: 20240002909
    Abstract: The present disclosure relates to novel methods of discriminating and/or detecting mis-matched polynucleotide populations in a sample by determining the ratios of mismatched polynucleotide species after specific enzymatic digestion treatment. Aspects of this disclosure includes obtaining, enhancing and/or determining the amount of one DNA or RNA species versus another in a given sample following enzyme digestion treatment; determining the relative abundance of the species contained in the sample based on the changes in the relative ratios following enzymatic treatment.

  • Publication number: 20220195403
    Abstract: A method is disclosed for highly efficient DNA sequence alterations. The method is useful for editing chromosomes, to engineer cellular markers through insertion of genes, or to create epigenetic changes by using cas9-enzyme fusions where the enzymes can be DNA epigenetic modifying enzymes or chromatin modifying enzymes, etc. The technology also differs from all previously known technologies in that the CRISPR/Cas system can function in ways that are “clean”, i.e. they have not been in contact with any virus, or are carried DNA molecules that can insert into the chromosome in unintended locations.

  • Patent number: 10435711
    Abstract: The present disclosure relates generally to novel methods and compositions for using engineered reprogramming factor(s) for the creation of induced pluripotent stem cells (iPSCs) through a kinetically controlled process. Specifically, this disclosure relates to establishing combinations of reprogramming factors, including fusions between conventional reprogramming factors with transactivation domains, optimized for reprogramming various types of cells. More specifically, the exemplary methods disclosed herein can be used for creating induced pluripotent stem cells from various mammalian cell types, including human fibroblasts. Exemplary methods of feeder-free derivation of human induced pluripotent stem cells using synthetic messenger RNA are also disclosed.

  • Publication number: 20170044608
    Abstract: A multi-step method is disclosed for efficient selection of antibody or antibody fragments. In addition to the dramatically increased efficiency of finding antibodies against a given immunogen by the invented processes, the novel technology also differs from all previously known technologies in that the antibody or antibody fragments represent the most abundant antibodies induced by the immunogen, therefore having the highest potential of specificity and affinity. Utility of the invention can be found in virtually all areas that involve antibody or T cell receptor selection using any animal, against any immunogen.
