BactoBeads™ are non-pathogenic, freeze-dried microbes (bacteria and lower eukaryotes) that are easily cultured for use in the classroom. Each bead contains microorganisms, buffer, salts and nutrient broth in an instantly soluble pellet.
Biotechnology Basics - qPCR
PCR exponentially amplifies copies of a DNA sequence and it’s great at producing more DNA for subsequent analysis. For example, PCR combined with gel electrophoresis can tell us whether a particular loci is present or absent. It’s also somewhat of a black box - you put your sample in a thermal cycler, program in the cycles’ temperatures, and later on come back and collect your product. We know what happens in between but we can’t see it happening in real time.

Top 100 Papers in Biotechnology -- and How to Bring Them Into Your Classroom
In order to communicate their findings to others in their field, scientists will publish their data in peer-reviewed journals. Some of the techniques within these papers have revolutionized the way we do science. Recently, a leading science journal tabulated the top 100 most cited scientific research articles ever. Many of the techniques within these papers are used in the research lab every day!

The Evolution of Plants
From still unknown flowers, trees, ferns and mosses in the rainforest to the vegetables and grain we eat at home, plants share a deep and in many ways still mysterious history. This history has shaped the evolution of the other kingdoms as well as the physical properties of Earth itself.

Five Viruses You Should Know About
In the late 1800’s, scientists were working to characterize the means through which microbes caused disease. While certain diseases like cholera, tuberculosis and anthrax could be explained by the presence of specific bacteria, other diseases, like rabies, could not. As such, these agents were considered to be a “biological chemical”; accordingly, they were named virus, from the Latin word referring to poison or other venomous compounds.

Lighting Up Life With GFP
Meet the luminescent Aequorea victoria. This jellyfish lights up the eastern Pacific Ocean with a green fluorescent signal. Producing this signal is a two steps process. First a blue light is created through an interaction between released calcium (Ca2+) and the protein aeqorin. Then the blue light is turned green by a protein known as Green Fluorescent Protein (GFP). Both proteins have become powerful tools in biotechnology.
