Biotechnician 2A: Moving into the Lab

Unit 1: Managing a Biotech Laboratory

A biotechnology laboratory is a vibrant, exciting place to work, but there are also many potential hazards if supplies and equipment are not well cared for or are used incorrectly. Each lab presents its own unique safety challenges, but one thing is for sure: safety is the responsibility of every member of the research team! The proper labeling, inventory, and storage of all solutions and chemicals is also a joint responsibility. Every team member should exhibit the highest level of ethical behavior and practice professional work habits to ensure the laboratory is safe and effective for all.

Unit 2: Experimental Design

Did you know that scientists have created mice, monkeys, cats, and even a beagle that “glow in the dark”? These experimental animals are assets for researchers in the study of diseases such as cancer, Parkinson’s, and diabetes. And it all started with a simple experimental question: why does the jellyfish A. victoria glow in the dark? From here, the scientific method was deployed to learn about a green fluorescent protein (GFP) and even identify the gene that codes for it. The discovery and applications of the GFP are shining examples of scientific ingenuity at its finest and serve as an exemplary model of good experimental design. By learning about the journey of the GFP—from curiosity to application—you can apply these methods to your own experimental design someday!

Unit 3: The Spectrophotometer & the Microscope

A biotechnologist often relies on a dynamic duo of tools in the lab: the microscope and the spectrophotometer. If you intend to purify a protein or the gene coding for a protein, how do you quantitate its purity after each step of your procedure? Spectroscopy can be used to do just this! Spectroscopy is also used to measure enzyme activity and perform routine tests that monitor the health of your heart, kidneys, and liver. How do you observe objects that are invisible to the naked eye? The microscope can visualize cells and tissues using various lenses to magnify the images up to 500,000 times their original size! Both of these tools equip the biotechnician to quantitate macromolecules and visualize living cells. How would you use these tools if you were working in a lab?

Unit 4: Preparing Solutions

One of the first things a biotechnician does each morning is prepare their solutions for the day. Understanding formulas to properly create solutions and buffers is essential to success—and safety—in the lab environment. One wrong calculation can cause disastrous results. The measure of concentration in the laboratory is molarity or moles per liter. This measure is used in making solutions and buffers, diluting solutions, and more. Math and science go hand in hand—especially in the biotechnology lab. Everyone in the lab must measure correctly and calculate with precision to ensure that experiments are reliable and that everyone is safe. Get your calculators ready—it’s time to prepare our solutions!

Unit 5: Bacteria in Biotechnology

Did you know that the total number of bacterial cells in your body outnumbers your human cells? Most bacteria in the body are helpful, but harmful bacteria have the potential to be lethal. Before the discovery of antibiotics, bacteria caused plagues that killed millions of people. We now grow and culture bacteria in the biotechnology laboratory to create products that save lives. Let’s learn all about bacteria and its impact on the field of biotechnology!

Unit 6: Genetically Engineering Bacteria

Bacteria have made genetic engineering possible. Through the miracle of recombinant DNA technology, a desired human gene can be selected and inserted into a bacterial plasmid. Once the recombinant plasmid is taken up by bacteria, it is gene expressed by the normal cellular machinery because all life recognizes the same genetic code. In this way, a human protein can be made by bacteria on an industrial scale. Biotechnology has turned bacteria into microscopic factories that produce drugs and proteins that help mankind. Let’s learn more about this process and how you can design your own genetic engineering experiment!
