摘要:
This present disclosure relates to a method of producing a proteoglycan having anticoagulant activity, comprising of and providing a cell transfected with a recombinant nucleic acid encoding a core protein having one or more glycosaminoglycan attachment sites; and incubating the cell under conditions to promote the production of a proteoglycan comprising the core protein linked to heparin and/or HS and optionally other glycosaminoglycan chains, and to heparin or heparan sulphate isolated from such proteoglycans that have significant anti-coagulant activity. The invention also relates to a recombinant proteoglycan comprising a core protein and heparin and/or heparan sulfate, to a cell capable of producing a proteoglycan comprising the core protein and heparin and/or heparan sulfate, and to a method of treating or preventing blood coagulation, or a condition associated with blood coagulation, using the recombinant proteoglycan comprising a core protein and heparin and/or heparan sulfate and/or the heparin and/or heparan sulfate isolated from such proteoglycans.
摘要:
The present invention relates to nucleic acid molecules comprising a nucleic acid sequence encoding a membrane-bound biotin mimetic peptide (BMP) or biotin acceptor peptide (BAP). The invention also relates to a method for selection of high producer cells secreting a protein of interest.
摘要:
The present invention relates to nanoparticles and their use to form nanocomposite material, in particular bionanocomposite material, specifically wherein the nanoparticles are formed using plant virus attached to a scaffold of cellulosic material and/or cellulose derived materials, in particular wherein said cellulosic material further comprises plant cell components, for example hemicellulose, pectin, protein or combinations thereof.
摘要:
Multi-domain recombinant proteins have a cutinase catalytic domain. The cutinase catalytic domain is a modular domain, which may be combined with other protein domains that also function in a modular fashion. For example, the cutinase catalytic domain can be operably linked to a polymer binding domain via a linker domain (e.g., a threonine/proline-rich linker polypeptide). The cutinase catalytic domain can be from an endogenous cutinase having a multi-domain modular organization, such as from the actinobacterium Kineococcus radiotolerans. The recombinant proteins are used in compositions, methods and uses, such as for use in industrial applications.
摘要:
The present invention provides a sensitive and specific indirect homogeneous mobility shift assay using size exclusion chromatography to measure biologics such as vedolizumab and ustekinumab in a patient sample. The assays of the present invention are particularly advantageous for detecting the presence or level of biologics that target complex or large antigens including cell surface proteins, transmembrane proteins, heavily glycosylated proteins, and multimeric proteins, as well as antigens that cannot be purified, impure antigens, and partially or substantially purified antigens. The present invention also provides isolated soluble α4β7 integrin heterodimers and isolated soluble IL-12p40 monomers that are suitable for use in the indirect assays described herein.
摘要:
Disclosed are peptides that induce an active plant response, but not a hypersensitive response, when applied to plant tissue. These peptides also preferably exhibit improved solubility, stability, resistance to chemical degradation, or a combination of these properties. Use of these peptides or fusion polypeptides, or DNA constructs encoding the same, for modulating plant biochemical signaling, imparting disease resistance to plants, enhancing plant growth, imparting tolerance to biotic stress, imparting tolerance and resistance to abiotic stress, imparting desiccation resistance to cuttings removed from ornamental plants, imparting post-harvest disease or post-harvest desiccation resistance to a fruit or vegetable, or enhancing the longevity of fruit or vegetable ripeness are also disclosed.
摘要:
A method for detecting an interaction between one or more protein bait and one or more candidate prey in a eukaryotic cell, comprising the steps of: a) providing an eukaryotic cell expressing (i) one or more protein bait, and (ii) one or more candidate prey, wherein said protein bait comprises a bait moiety and a polymerized-tubulin binding moiety. b) determining the occurence of an interaction between said one or more protein bait and said one or more candidate prey in the eukaryotic cell, wherein said protein bait is bound to polymerized tubulin in the eukaryotic cell, thereby localizing said one or more candidate prey along said polymerized tubulin, thereby detecting said interaction.
摘要:
The present disclosure relates to antibodies and proteins comprising an antigen-binding portion thereof that specifically bind to the pro-inflammatory cytokine IL-17A and a peptide tag that binds hyaluronan (HA). The disclosure more specifically relates to specific antibodies and proteins that are IL-17A antagonists (inhibit the activities of IL-17A and IL-17AF) and are capable of inhibiting IL-17A induced cytokine production in in vitro assays, and having an inhibitory effect in an antigen-induced arthritis model in vivo. The disclosure further relates to compositions and methods of use for said antibodies and proteins to treat pathological disorders that can be treated by inhibiting IL-17A or IL17AF mediated activity, such as rheumatoid arthritis, psoriasis, systemic lupus erythematosus (SLE), lupus nephritis, chronic obstructive pulmonary disease, asthma or cystic fibrosis or other autoimmune and inflammatory disorders.
