20090187999 | Process for Producing Exogenous Protein in the Milk of Transgenic Mammals and a Process For Purifying Proteins Therefrom - The invention relates to a non-human transgenic mammal that is useful for the production of a protein of interest that may be toxic to the mammal. The mammal is characterized by the fact that it is transgenic for the production in its milk of an inactive form of the protein of interest, preferably recombinant human insulin. It is not possible to produce recombinant human insulin in transgenic mammals since this molecule has a certain degree of biological activity in the mammals and could be toxic to the mammal. Thus, the invention involves cloning a genetic construct comprising a sequence encoding a modified human insulin precursor under the control of a beta casein promoter in an expression vector. It also involves transfecting the expression plasmid into fetal bovine somatic cells, such as fibroblasts, and enucleating bovine oocytes by nuclear transfer to generate transgenic embryos. The invention gives rise to transgenic bovine that will be able to produce a modified human insulin precursor in their mammary glands. Afterwards, the milk of these transgenic mammals can be collected, the modified human insulin precursor can be converted in vitro into recombinant human insulin, and the recombinant human insulin can be purified to homogeneity as a pure biopharmaceutical product. | 07-23-2009 |
20100125918 | ENTEROVIRUS TYPE 71 PROTEIN AND METHOD FOR PRODUCTION - The invention provides a new type of a capsid protein VP1 of human enterovirus 71, named as MEL701-VP1 and functional/structural variants thereof, which is used for protection against enterovirus. The transgenic animal producing the protein, the composition comprising the protein and the method for production thereof are also provided. | 05-20-2010 |
20100162418 | RECOMBINANT PROTEIN S COMPOSITION - A pharmaceutical agent for treating a disease such as inflammatory diseases, blood coagulation diseases associated with deficiency of Protein S has been required. The present invention provides a Protein S composition comprising recombinant Protein S molecules having complex type N-glycoside-linked sugar chains, wherein the Protein S has a higher binding activity to a receptor for advanced glycation end products (hereinafter referred to as “RAGE”) than native Protein S present in healthy human blood, and also has a higher ratio of sugar chains in which fucose is not bound to the complex type N-glycoside-linked sugar chains bound to Protein S than native Protein S present in healthy human blood. | 06-24-2010 |
20100205680 | MAMMARY GLAND- SPECIFIC HUMAN ERYTHEROPOIETIN EXPRESSION VECTOR, TRANSGENIC ANIMAL AND METHOD FOR PRODUCING HUMAN ERYTHROPOIETIN USING SAME - The present invention provides a mammary gland-specific human erythropoietin expression (hEPO) vector, transgenic animal and method for producing human erythropoietin using the same. The inventive hEPO-expressing transgenic animals express a mammary gland-specific EPO at an extremely higher concentration than the convention method. The hEPO produced from inventive transgenic animals shows better stability and superior physiological activity than those of the same kind of commerally available protein. Therefore, the inventive hEPO-expressing transgenic animals can be effectively used for production of EPO showing a superior physiological activity than the existing EPO. | 08-12-2010 |
20100293623 | Rabbit nuclear cloning method and uses thereof - The invention concerns a method for producing non-human mammal embryos, in particular rabbit by nuclear cloning. The invention also concerns the mammals obtained and their uses. | 11-18-2010 |
20110072526 | PROCESS FOR PRODUCING EXOGENOUS PROTEIN IN THE MILK OF TRANSGENIC MAMMALS AND A PROCESS FOR PURIFYING PROTEINS THEREFROM - The invention relates to a method of producing a protein of interest, comprising making a non-human transgenic mammal that produces said protein in its milk, obtaining said milk from the non-human transgenic mammal and purifying said protein of interest from the milk. Transgenic bovine animals were generated, which are able to produce human growth hormone in mammary glands. The method involves cloning of a genetic construct comprising the hGH gene and beta casein promoter sequences conveniently in an expression vector. It also includes transfection procedures into fetal bovine somatic cells, generally fibroblasts, and the nuclear transfer into enucleated bovine oocytes, generating thus transgenic embryos. The method also includes other procedures to generate transgenic embryos for further expansion of the transgenic herd, such as the subcloning of transgenic female bovines, the superovulation of transgenic cows and their insemination with semen from a non-transgenic or a transgenic male bovine, and the superovulation of non-transgenic cows and their insemination with semen from a transgenic male bovine. Afterwards, transgenic embryos give rise to transgenic cattle that produce human growth hormone in huge amounts in their milk, from which the hormone is completely purified and analysed to fulfill all the requirements for the manufacture of a pure biopharmaceutical product. | 03-24-2011 |
