Categories of Biotech Companies
Biotechnology Companies fall into one of 4 categories based on the products they make/sell • • Industrial and Environmental Medical/Pharmaceutical Agricultural Diagnostic Research
Industrial/Environmental Biotechnology
Fermented Foods and Beverages
Medical/Pharmaceutical Biotechnology
Agricultural Biotechnology
Diagnostic Research Biotechnology PCR ELISA DNA Fingerprinting
Biotech Firm
Discovery of antibiotics • Significant impact on life • Companies are looking for NEW antibiotics • Cipro is a new antibiotic
Use of restriction enzymes and ligase revolutionized biotechnology research and development
Recombinant DNA can be inserted into cells which will give the cells new characteristics—genetically modified organisms (GMOs)
Luciferase gene makes plant glow— transferred from fireflies
Flounder gene in strawberries
Flounder gene in tomatoes
Transgenic technology enables goats to secrete t. PA in their milk
Applications of r. DNA and genetic engineering technologies E. coli are now engineered to manufacture the blue dye of denim jeans from glucose.
How Companies Select Products to Manufacture • Develop Ideas for New Products. • Research and Development. • Product Development Plan.
Product Identification and Development Plan • Does the product meet a critical need? • Is the market large enough to produce enough sales? • Can patent protection be secured? • Can the company make a profit?
Matter of Economics • Interferon beta-1 b helps some people with a certain kind of multiple sclerosis. • Costs $20, 000 + per patient per year. • British researchers calculated what it would cost and decided the funds could be spent better in another area.
Recent Biotech product—Pulmozyme It cuts extracellular DNA left behind by dying WBCs who were fighting the bacteria. This keeps the mucus from becoming too thick
