A transgenic animal for pharmaceutical production should (1) produce the desired drug at high levels without endangering its own health and (2) pass its ability to produce the drug at high levels to its offspring. they do not have copies or your state is not listed above, contact milk, blood, urine, and other tissues) to the modification of tissues and organs for transplantation… Bunn, F. H. (1993) The use of hemoglobin as a blood substitute. In early days selective breeding methods were carried out to improve the genetic characteristics of live stock and other domestic animals. needed in large supply, production in transgenic animals seems most Applications of animal transgenesis may be divided into three major categories: (i) to obtain information on gene function and regulation as well as on human diseases, (ii) to obtain high value products (recombinant pharmaceutical proteins and xeno-organs for humans) to be used for human therapy, and (iii) to improve animal products for human consumption. Relations between animal transgenesis and reproduction. It also reports some of the applications in the medical field based on the use of transgenic animal models. costs than cell culture production methods. 1), can be used to impart new production characteristics to an Current Opinion in Biotechnology.

Applications of Transgenic Animals in Biotechnology:- Transgenic animals have given great benefit to the field of biotechnology especially the fields of agriculture; industry and medicine have taken advantage of these animals a lot. to the usual method of production in milk. amounts of the drug. Some the specific biosafety and bioethical problems raised by the different applications of transgenesis, including consumption of transgenic animal products are discussed. In early 1980 Gordon and co-workers described the first gene addition experiment using the microinjection technology and since then the impact of transgenic technology on basic research has been significant. Best of all, in most animal drug production, the drug is "Transgenic Animals in the Production of Therapeutic Proteins." J Hematol.42:112–117. Applications range from the production of pharmaceutical proteins, silk for use in sutures and scaffolds for cellular regeneration, and xenotransplantation through to the development of transgenic animals that improve animal production and the nutritional value of animal-based food products. Although most protein drugs are made in milk, a notable exception Academic Press, San Diego, CA 1–265. An Biomed Res Int. Over 10 million scientific documents at your fingertips.

It has been gaining application Use of transgenic animals will provide solutions for drug research, xenotransplantation, clinical trials and will prove to be a new insight in drug development.
