  • Patent number: 10281473
    Abstract: The application discloses compositions, methods, systems, and apparatuses for rapid sequence analysis of proteins, including location of post-translational modifications and disulfide bonds. Limited digestion of fully denatured antibody occurs in seconds by flowing sample in 8M urea at constant pressure through a micro column reactor containing immobilized aspergillopepsin I, resulting in a product mixture containing 3-10 kDa peptides, which is then fractionated by capillary column chromatography and analyzed by both electron transfer dissociation (ETD) and collision activated dissociation mass spectrometry. This method provides 95% sequence coverage of a mAb and detects numerous post-translational modifications. For disulfide bond location, native mAb is subjected to longer digestion times. Release of disulfide containing peptides from accessible regions of the folded protein occurs with short digestion times.

  • Patent number: 9539610
    Abstract: A method for electroless coating of a substrate by applying an activating coat of polyelectrolyte or salt with a first aqueous composition, rinsing of the activating coat such that the activating coat is not entirely removed The activated surface that has remained after rinsing is then contacted with an aqueous composition in the form of a solution, emulsion or suspension to form an organic secondary coat (precipitation coat), and drying. The activating coat contains at least one cationic polyelectrolyte or at least one cationic salt in solution in water. The aqueous composition which forms the secondary coat contains constituents which can be precipitated, deposited and/or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, which is made of the activating coat and the secondary coat, has a thickness of at least 1 ?m.

  • Patent number: 9429583
    Abstract: A system and method for the detection and quantification of fragile X mental retardation protein (FMRP) in human tissue and blood samples. The system includes several high avidity monoclonal antibodies that may be provided on Xmap microspheres to capture FMRP from a tissue or blood specimen. The resulting complex is reacted with a polyclonal anti-FMRP rabbit antibody and then mixed with an anti-rabbit IgG antibody conjugated to phycoerythrin. Fluorescence emitted from the resulting complex is a function of the amount of FMRP present in the specimen.

  • Patent number: 9289454
    Abstract: A method for producing multilayered cell sheets, including producing a vascular bed which includes an artery-vein loop and in which a capillary vascular network is constructed; layering cell sheets on the vascular bed; and perfusing a culture medium in vitro to construct a vascular network in the cell sheets. The production method enables vascular networks to be constructed in cell sheets and enables thick multilayered cell sheets to foe easily produced by layering the cell sheets. Such thick multilayered cell sheets are useful as in vivo tissue-like products for regenerative medicine for various tissues and for evaluation of drugs and the like.

  • Patent number: 9243224
    Abstract: A cell culture medium with high content of choline chloride is provided. The cell culture media further comprise only moderate amounts of amino acids, in particular the amount of glutamine in the cell culture media is limited. The cell culture media can be used for large scale production of polypeptides using cell cultures. The cell culture media with high content of choline chloride are particularly suitable for fed-batch cell culture whereby cell viabilities stay at a higher level for a longer time and high polypeptide titers although limited amounts of amino acids are used.
