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.
Edvotek Road Trip - A Brief Tour of the West Coast!
A few weeks ago, Edvotek kicked off our Fall Conference Schedule by attending the yearly meeting for the California Science Teachers Association in Sacramento, California. Before the conference started, we had time to wander around the city and take in the sites. Our first stop was Old Sacramento, which is the oldest part of town. We had fun wandering the cobblestone streets and the historic buildings. In fact, we stopped at the B. F. Hastings Building, which served as the western terminal of the Pony Express. We also toured the historic California State Capitol.

DNA Ligase - Building a Bridge with DNA
DNA ligase is one of the most important, but least celebrated, enzymes used in modern biotechnology. This enzyme plays a very important role in DNA replication and repair by acting like a “glue” that can connect different DNA fragments to one another. Scientists take advantage of this molecular glue to combine DNA fragments to make an entirely new sequence. However, many people are merely using DNA ligase as a tool without knowing the story and mechanism behind it.

Visualizing DNA After Agarose Gel Electrophoresis
Electrophoresis is a technique that allows us to separate DNA, RNA or proteins into bands according to their size. For more information about this technique, be sure to check out our previous post describing electrophoresis.
