摘要:
The invention features methods of producing an antibody in the milk of a transgenic mammal. The methods include providing a transgenic mammal whose somatic and germ cells comprise a sequence encoding an exogenous heavy chain variable region or antigen binding fragment thereof, at least one heavy chain constant region, or a fragment thereof, and a hinge region, operably linked to a promoter which directs expression in mammary epithelial cells, wherein said hinge region has been altered from the hinge region normally associated with the heavy chain constant region. The invention also features transgenic mammals, methods of producing these mammals, compositions comprising such antibodies, and nucleic acids encoding the antibodies.
摘要:
Apparatus and method for separation of milk and milk products, e.g., involving sequential separation of milk, colostrum, and whey components by cross-flow filtration. The apparatus and method in a preferred aspect employ cross-flow filtration, chromatography and fermentation to separate and fully utilize the components of milk, colostrum, and whey to generate numerous individual components, minimize waste, lower adverse environmental issues and provide enhanced economic benefits to dairy producers. A wide variety of consumer and nutraceutical products can be produced from the fractions and/or sub-fractions of milk products obtained from such separation. The invention further contemplates a methodology for selecting optimum membrane, device, and operating conditions to achieve a desired separation.
摘要:
The present invention is related to the separation of whey proteins, particularly the sequential separation of whey proteins into separate fractions through the use of chromatography. The present invention further provides methods and compositions for the sequential separation of whey proteins, as well as their use in various products. The present invention also provides methods and compositions for the cleaning of chromatography resins used in the separation of whey proteins.
摘要:
The invention is directed to a method and food product for achieving at least one of the following: increasing muscle protein or reducing fat in an animal. The method comprises administering to the animal an effective amount of a composition comprising a gastrointestinal neuro-modulator antibody in order to neutralize the gastrointestinal neuro-modulator.

摘要:
Three mammalian are disclosed which are useful in the diagnosis and prognosis of tumors of lymphoid and epithelial origin. The three proteins are immunologically related to each other. The level of expression of the proteins correlates with the malignant potential of lymphoid and epithelial tumors. In addition, in some cases the subcellular location of the proteins is indicative of malignant potential. Antibodies reactive with the proteins are disclosed as diagnostic tools, as are nucleic acid probes and primers for quantitating the messenger RNAs encoding the proteins. Methods for preparing and purifying the proteins are also taught.
摘要:
The invention relates to the use of colostral milk or colostral milk preparations from the cow, or fractions containing immunoglobulin prepared therefrom, as a liver protective preparation for the prevention and treatment of liver function disturbances in liver diseases, especially for the prevention of the sequelae of these diseases, such as portal encephalopathy.
摘要:
Recombinant proteins have been developed for the immunization of animals against cryptosporidiosis. The Proteins are effective for the immunization of a variety of animals against Cryptosporidium parvum, particularly for the production of hyperimmune colostrum that may be used to confer passive immunity against the parasite. Isolated DNA sequences which encode these proteins have also been developed. The DNA sequences may be inserted into recombinant DNA molecules such as cloning vectors or expression vectors for the transformation of cells and the production of the proteins.
摘要:
The present invention relates to methods for purifying heterologous antibodies from caprine milk, such as goat milk. The present invention includes protein A based affinity chromatography to obtain purified transgenically expressed antibodies, in particular concentrates free from endogenous caprine antibodies.
