  • Patent number: 11667906
    Abstract: Magnetic microcarrier beads have a particle size of 1 to 1000 micrometers and include a composite core and a polymer coating that surrounds and encapsulates the core. The composite core includes magnetic particles embedded within an indigestible polymer matrix. The coating is a digestible or indigestible polymer that facilitates cell adhesion to the surface of the beads during cell culture. Magnetic force can be used to agitate the microcarrier beads during cell culture as well as to separate the beads from cultured cells or processed bio-media.

  • Patent number: 11629364
    Abstract: The present invention includes methods for preparing anticoagulant polysaccharides using several non-naturally occurring, engineered sulfotransferase enzymes that are designed to react with aryl sulfate compounds instead of the natural substrate, PAPS, to facilitate sulfo group transfer to polysaccharide sulfo group acceptors. Suitable aryl sulfate compounds include, but are not limited to, p-nitrophenyl sulfate or 4-nitrocatechol sulfate. Anticoagulant polysaccharides produced by methods of the present invention comprise N-, 3-O-, 6-O-sulfated glucosamine residues and 2-O sulfated hexuronic acid residues, have comparable anticoagulant activity compared to commercially-available anticoagulant polysaccharides, and can be utilized to form truncated anticoagulant polysaccharides having a reduced molecular weight.

  • Patent number: 11629174
    Abstract: Disclosed is a high-throughput transcriptional assay format in Actinomycete bacteria, and Streptomyces spp. in particular, that leverages eGFP, inserted both at a neutral site and inside the biosynthetic cluster of interest, as a read-out for secondary metabolite synthesis. Using this approach, a silent gene cluster in Streptomyces albus J1074 was induced. The cytotoxins etoposide and ivermectin were revealed as potent inducers, allowing the isolation and structural characterization of nearly 20 novel small molecule products of the chosen cluster. One of these molecules is a novel antifungal, while several others inhibit a cysteine protease implicated in cancer. Studies addressing the mechanism of induction by the two elicitors led to the identification of a pathway-specific transcriptional repressor that silences the gene cluster under normal growth conditions.

  • Patent number: 11614441
    Abstract: The present invention provides a method for evaluating effectiveness of a cell therapeutic agent. When using TGF-? and/or TSP-1 expression level(s) in: (a) a first population of transformed mammalian cells with TGF-?; and (b) a second population of untransformed mammalian cells with the same gene, respectively, as a criterion for determining effectiveness of a cell therapeutic agent, and whether or not expression thereof, it is possible to definitely determine the therapeutic efficacy of each cell therapeutic agent prior to initiation of the treatment. In addition, since use of a cell therapeutic agent without therapeutic effects is avoided, undesired procedures and side effects may not be entailed.

  • Patent number: 11597955
    Abstract: An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process), with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.
