  • Patent number: 11352650
    Abstract: The invention provides a genetically modified micro-organism for intracellular biosynthesis of a cellular metabolite, comprising a synthetic error correction system having a penalty gene, whose expression leads to arrested growth or cell death (e.g. a toxin gene) in combination with a survival gene, whose expression provides an antidote that restores cell viability and normal growth (e.g. a cognate antitoxin gene). Alternatively, the system has a survival gene, alone, whose expression is essential for growth (i.e. essential gene). The synthetic error correction system further comprises a biosensor, whose function is to induce expression of the survival gene which leads to cell growth, only, when the cell produces a pre-defined level of a given metabolite.

  • Patent number: 11335547
    Abstract: A separation device separates an unknown intact mAb or reduced mAb subunits of a known mAb class from a sample. An ion source device ionizes the mAb. A mass spectrometer fragments the ionized mAb using an ECD device and mass analyzes resulting product ions using a mass analyzer, producing one or more product ion spectra. Theoretical product ion peaks are calculated for one or more constant portions of the mAb class. The theoretical product ion peaks are removed from the one or more product ion spectra, producing one or more difference product ion spectra. De novo sequencing is applied to the one or more difference product ion spectra, producing one or more candidate sequences for one or more variable portions of the mAb. A genome database is searched for matches to the one or more candidate sequences, producing one or more matched sequences for the one or more variable portions.

    Abstract: A method of producing novel bacteriophages with expanded host-range and bacteriophages with expanded host ranges are disclosed. The method produces mutant phage strains which are infectious to a second host and can be more infectious to their natural host than in their natural state. The method includes repeatedly passaging a selected phage strain into bacterial cultures that contain varied ratios of its natural host bacterial strain with a bacterial strain that the phage of interest is unable to infect; the target-host. After each passage the resulting phage are purified and screened for activity against the target-host via double-overlay assays. When mutant phages that are shown to infect the target-host are discovered, they are further propagated in culture that contains only the target-host to produce a stock of the resulting mutant phage.

The method includes the step of producing multiple single stranded primary DNA constructs having (a) partially overlapping and complementary internal regions that together define the target DNA, and (b) flanking regions on either side of the internal regions containing a PCR primer recognition site and a restriction enzyme recognition site. The primary DNA constructs are amplified to form a pool of double-stranded primary constructs, and a restriction enzyme is used to cleave off the flanking regions. The target double-stranded DNA is then assembled from the cleaved fragments. Hundreds of thousands of oligonucleotides can be synthesized and quickly and efficiently assembled into many different individual double-stranded DNA target sequences using this method.

Some preferred embodiments of BtB have removed proteinase cleavage sites resulting in increased stability of the modified BtB in the insect gut, while retaining the ability to enhance B.t. proteins for improved insect control. In some preferred embodiments, the protease-stable BtB is used in combination with B.t. spores and/or crystals comprising a Cry protein. Also reported herein is the significant and increased enhancement of Bt toxins against relatively Bt-tolerant insects (Helicoverpa zea, Spodoptera exigua and Agrotis ipsilon), when used with BtBs. We also describe increased toxin enhancement with cadherin fragments that are stabilized against over-digestion by insect midgut proteinases.

  • Publication number: 20150119254
    Abstract: An object of the present invention is to develop and provide a method for efficiently producing a nucleic acid aptamer, particularly, a DNA aptamer, having higher specificity and binding activity against a target substance than those of nucleic acid aptamers obtained by conventional methods. The present invention provides a transcribable or replicable nucleic acid aptamer comprising a natural nucleotide and a non-natural nucleotide having an artificial base-pairable artificial base. The present invention also provides a method for sequencing a non-natural nucleotide-containing single-stranded nucleic acid molecule selected from a single-stranded nucleic acid library.

  • Publication number: 20150110836
    Abstract: The present disclosure provides compositions and methods for the generation of an antibody or immunogenic composition, such as a vaccine, through epitope focusing by variable effective antigen surface concentration. Generally, the composition and methods of the disclosure comprise three steps: a “design process” comprising one or more in silico bioinformatics steps to select and generate a library of potential antigens for use in the immunogenic composition; a “formulation process”, comprising in vitro testing of potential antigens, using various biochemical assays, and further combining two or more antigens to generate one or more immunogenic compositions; and an “administering” step, whereby the immunogenic composition is administered to a host animal, immune cell, subject or patient. Further steps may also be included, such as the isolation and production of antibodies raised by host immune response to the immunogenic composition.

    Abstract: The invention relates to a method for selecting a sequence set from a library of expressed nucleic acid sequences, wherein cells are provided, each cell comprises an expressed nucleic acid sequence expressed as a target protein. The cells are encapsulated by treating them with a cationic polysaccharide and subsequently treating them with an anionic polysaccharide, yielding encapsulated cells, perforating the membrane of the encapsulated cells, yielding solubilized compartments, contacting them with a ligand to said target protein, the ligand bearing a detectable label, and selecting a subset of solubilized compartments as a function of detectable label and isolating the expressed nucleic acid sequences from the selection as a selected sequence set.

  • Publication number: 20140342918
    Abstract: The disclosure relates to a switchable aptamer having a high affinity for a selected target such as a virus, cell or antibody when in the presence of a binding ion and a low affinity for said target in the absence of said binding ion. The switchable aptamer may be isolated from a pool comprising a mixture of aptamers by incubating the pool with the target ligand and a binding ion to form target-aptamer complexes; separating unbound aptamer molecules from the target-aptamer complexes; contacting the target-aptamer complexes with a chelating agent having affinity for the binding ion wherein a switchable aptamer specific to said target is released from the target-aptamer complexes; and isolating the switchable aptamer released in the preceding step.

  • Publication number: 20140302999
    Abstract: The present invention is directed to a method for obtaining an in vitro pharmacological model of a recombinant protein drug in a given host. A plurality of biomolecules are selected which are known or suspected to influence pharmacology of the recombinant protein in the host via a binding interaction with the recombinant protein. The recombinant protein is contacted with each selected biomolecule and the binding kinetics parameters for each interaction are determined using a binding assay. These steps are then repeated with all selected biomolecules to produce a plurality of binding kinetics parameters for the selected biomolecules. The combined results provide an in vitro pharmacological model of the recombinant protein in the host. The in vitro pharmacological model may then be used in several applications, such as optimizing new batches of recombinant protein drugs, developing biosimilar or bio-better drug candidates.
