Expression Cloning *
|Time Required||Average (6-10 days)|
|Prerequisites||Some laboratory experience is required: knowledge of sterile technique, working with bacterial cultures, and using automatic pipettes are all helpful.|
|Material Availability||This science project requires the purchase of Bio-Rad's pGLO Bacterial Transformation Kit. Details about how to order products from Bio-Rad can be found here.|
|Cost||Very High (over $150)|
|Safety||Adult supervision is required in the laboratory facility. Use sterile technique. Read the Microorganisms Safety Guide before starting any experiments. SRC approval may be necessary.|
AbstractWhat is cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate bacterial expression with the pGLO Bacterial Transformation Kit from the Bio-Rad Biotechnology Explorer Program to make bacteria express green fluorescent protein (GFP), as shown in Figure 1, below (see the Science Buddies project, Bacterial Transformation Efficiency). With variations to this kit you can test the conditions for pGLO expression under different conditions. You can also combine with other kits to map the pGLO plasmid and purify the expressed pGLO protein using column chromatography. (Bio-Rad, 2006)

Biological TechnicianWhat do the sequencing of the human genome, the annual production of millions of units of life-saving vaccines, and the creation of new drought-tolerant rice varieties have in common? They were all accomplished through the hard work of biological technicians. Scientists may come up with the overarching plans, but the day-to-day labor behind biotechnology advances is often the work of skilled biological technicians. Read more
Biochemical EngineerA nice cool yogurt is the perfect snack. It comes in a variety of delicious flavors like peach, chocolate, and cherry and contains calcium, vitamins, and minerals that are good for you. Yogurt also contains live cultures that your body needs to maintain good health. How did all of those good things get into your yogurt? The answer is that a biochemical engineer helped to develop a recipe to make that yogurt a perfect snack for you. So many of the products that we use every day, from medicine and fertilizer to packaged foods, result from the hard work of a biochemical engineer. A biochemical engineer takes a recipe that has been formulated by a biologist or a chemist in the laboratory and develops it into a large-scale manufacturing process. Biochemical engineers design the manufacturing equipment that is required to convert raw materials into the products that you have at home, like cold tablets and packaged foods. If you are interested in applying your problem-solving skills to improving human lives, then you should definitely investigate this career. Read more
