  • Publication number: 20150105864
    Abstract: The invention provides a biocompatible silicone implant that can be securely affixed to living tissue through interaction with integral membrane proteins (integrins). A silicone article containing a laser-activated surface is utilized to make the implant. One example is an implantable prosthesis to treat blindness caused by outer retinal degenerative diseases. The device bypasses damaged photoreceptors and electrically stimulates the undamaged neurons of the retina. Electrical stimulation is achieved using a silicone microelectrode array (MEA). A safe, protein adhesive is used in attaching the MEA to the retinal surface and assist in alleviating focal pressure effects. Methods of making and attaching such implants are also provided.

  • Patent number: 8802394
    Abstract: Provided herein are methods for expressing proteins with disulfide bridges such as Vicrostatin (VCN), a chimeric variant of native snake venom disintegrin Contortrostatin (CN). The methods include what is believed to be a more efficient natural selection process that results in generating increased amounts of correctly-folded active conformers of proteins with disulfide bridges. In an aspect, this is achieved by growing Origami B cells in a more optimal redox environment during the induction of heterologous recombinant protein production.

  • Patent number: 8685668
    Abstract: This invention relates to methods of expressing eukaryotic proteins in prokaryotic hosts, particularly eukaryotic proteins that require formation of disulfide bridges for biological activity. Various approaches are used including fusion to thioredoxin, cytoplasmic expression of disulfide isomerases, deficiencies in thioredoxin and/or glutathione reductases, deficiencies in proteases, and the like. The method is applicable to express monomeric and dimeric forms of the eukaryotic protein with biological activity such as monomeric and dimeric forms of a disintegrin or a disintegrin domain. Included are the vectors, host cells expressing the proteins, the expressed proteins and methods of using the proteins.

  • Patent number: 6710030
    Abstract: The amino acid sequence of native contortrostatin was used in a cloning strategy to obtain full-length cDNA and deduced amino acid sequences for a contortrostatin precursor. The precursor includes pro-protein, metalloproteinase, and disintegrin (contortrostatin) regions of the multidomain protein. The sequences can be used produce recombinant DNA molecules which code on expression for contortrostatin proteins, including biologically active variants and fragments. When formulated as a pharmaceutically acceptable composition, the proteins can be used to treat patients by inhibiting disease processes associated with an integrin binding to an integrin receptor.
