The application of scientific and engineering principles on processing of material bybiological agents to provide goods and services primarily in pharmaceutical environment
Potential Benefits From Biotechnology• More accurate disease diagnosis and treatment• Improve crop yield, disease and stress resistance• Microbial production of chemicals, enzymes, food additives, pharmaceuticals, polymers, etc.• Livestock with enhanced genetic attributes• Elimination of pollutants and waste materials
Potential Social Concerns and Consequences of Biotechnology• Organisms harmful to other organisms or environment• Organisms reduce natural genetic diversity• Genetic engineering of humans?• Genetic privacy issues• Limited availability to poorer nations• Undermine traditional agricultural practices

Pharmaceutical Biotechnology Drug discovery 1. Receptor Technology: Natural product: - Medicinal plants - Intrinsic proteins (protein biotechnology) 2. Targeted drug discovery: bioinformatics screening computational High throughput screening
Pharmaceutical Biotechnology Drug delivery system development1. Chemical base: * Chemical modif ication * Liposome1. Immunological base: * Monoclonal Ab- conjugation
Biotech success storiesHuman Insulin (Humulin®) First FDA approved drug produced by rDNA technology. Insulin was extracted from the pancreas of cows and pigs. Amino acid sequence of bovine and swine insulins differed from the human sequence by a few AA.
Biotech success stories Human Insulin (Humulin®) Some diabetics produced antibodies to the animal insulin resulting in serious immune reaction. Humulin® eliminates adverse immune response to animal insulin No longer rely on animal sources for insulin.
Biotech success stories Human growth hormone(HGH) GH (pituitary gland) important regulator of growth during development. Children born with growth hormone deficiency become dwarfs. Regular injections of GH during development restores natural growth.
Biotech success stories Human growth hormone (HGH) Animal-derived GH is ineffective in humans. HGH isolated from the pituitary glands of human cadavers. Increased incidence of Creutzfeldt-Jakob disease in patients received HGH.
