Patent number: 11352445Abstract: Methods for preparing a recombinant protein from a bacterium are provided. The method includes constructing an expression vector including two promoters. Each of the two promoters attaches a secretion signal peptide to one polypeptide of a protein. The protein attached with the two promoters and secretion signal peptides is then cloned into the expression vector to provide a recombinant expression plasmid. The recombinant expression plasmid is transformed into a host cell. A fermentation process is performed to grow the host cell and to induce an expression to synthesize polypeptides in the host cell and to transport the polypeptides to an outside of a cytoplasm of the host cell, such that the polypeptides are released in a soluble form in a growth medium of the host cell. The polypeptides are assembled into a three-dimensional structure of the protein. The protein is captured from the growth medium.Type: GrantFiled: December 31, 2018Date of Patent: June 7, 2022Assignee: JECHO LABORATORIES INC.Inventors: Jianwei Zhu, Cedric Cagliero, Andrew Burnette, Yueqing Xie, Hua Jiang, Huili Lu, Manyu Luo

Patent number: 10323287Abstract: This invention relates in part to plant breeding and herbicide tolerant plants. This invention includes a novel aad-1 transformation event in corn plants comprising a polynucleotide sequence, as described herein, inserted into a specific site within the genome of a corn cell. In some embodiments, said event/polynucleotide sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. Additionally, the subject invention provides assays for detecting the presence of the subject event in a sample (of corn grain, for example). The assays can be based on the DNA sequence of the recombinant construct, inserted into the corn genome, and on the genomic sequences flanking the insertion site. Kits and conditions useful in conducting the assays are also provided.Type: GrantFiled: January 6, 2016Date of Patent: June 18, 2019Assignee: Dow AgroSciences LLCInventors: Yunxing Cory Cui, Jill Bryan, Donald Maum, Greg Gilles, Terry Wright, Jennifer Hamilton, Nicole Arnold, Nathan VanOpdorp, Tina Kaiser, Ning Zhou

Patent number: 10280211Abstract: The present invention relates to methods for screening and producing polypeptides that immunospecifically bind to an antigen, which: polypeptides comprise binding domains that are derived from rabbit immunoglobulin. Using rabbit antibody heavy-chain or light-chain scaffolds, the methods of the invention allow identification of novel CDR loops and framework regions that confer enhanced stability and/or affinity to isolated immunoglobulin variable domains, in particular, relative to those derived from rodent antibodies. The enhanced stability and/or affinity of the variable domains of the invention permit their use in the production research tools or therapeutic immunospecific polypeptides, including single domain immunospecific polypeptides, i.e., comprising one of a VH or VL domain.Type: GrantFiled: April 30, 2008Date of Patent: May 7, 2019Assignee: TECHNOPHAGE, INVESTIGAÇÃO E DESENVOLVIMENTO EM BIOTECNOLOGIA, SAInventors: João Manuel Braz Goncalves, Frederico Nuno Castanheira Aires Da Silva

Patent number: 10247745Abstract: The present teachings relate to methods, systems, and kits for the preparation, purification and/or analysis of a glycan or glycoconjugate, and specifically to a magnetic bead based sample preparation protocol that can enable full automation and reduced sample preparation time relative to current methods of glycoanalysis. In some aspects, the sample preparation protocol can provide for glycoconjugate capture, glycan release, fluorescent derivatization, and glycan purification for subsequent capillary electrophoresis, liquid chromatography, or other glycoanalytical method without requiring time-consuming sample preparation steps such as centrifugation or vacuum-centrifugation.Type: GrantFiled: April 27, 2015Date of Patent: April 2, 2019Assignee: Beckman Coulter, Inc.Inventors: Andras Guttman, Clarence Lew, Marton Szigeti, Csaba Varadi

Patent number: 10221403Abstract: The present invention provides a method of preparing zearalenone hydrolase, including the step of culturing a yeast cell carrying a gene encoding a zearalenone hydrolase in a medium to express a protein of the zearalenone hydrolase, wherein the medium contains 20 to 25% molasses by weight. This method provides a new strategy to efficiently prepare zearalenone hydrolase at low expenses.Type: GrantFiled: April 25, 2018Date of Patent: March 5, 2019Assignee: LIFE RAINBOW BIOTECH CO., LTD.Inventors: Ching-Kuo Yang, Yu-Hsiang Yu, Ya-Chieh Huang, Rou-Wan Liao
