Short note on :Transgenic cattle.

1.	Short note on :Transgenic cattle.
Answer» 1. Transgenic cattle are used for food production and for the production of human therapeutic proteins. 2. Transgenic cattle engineered with additional copies of bovine beta or kappa casein, show 8 to 20% increase in beta casein and a two-fold increase in kappa casein. 3. Various human proteins like Human lactoferrin, human alpha lactalbumin, human serum albumin and human bile salt stimulated lipase are expressed in the milk of transgenic cattle. 4. Transgenic cows produce factor IX (plasma thromboplastin component), used in the treatment of haemophilia. 5. Tracy, the transgenic cow born in Scotland, could produce a human protein in her milk for human therapeutics. 6. Human antibody products are made using transgenic cows that are immunized with a vaccine containing the disease agent. Antibodies are currently used for treatment of infectious diseases, cancer, transplanted organ rejection, autoimmune diseases and for use as antitoxins.
