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.
Fiber Evidence from Crime Scene Investigations
Criminal investigations have been used for centuries in an effort to fight crime. The techniques used have evolved over the years, and the field of forensic science can now solve more crimes than ever before. Modern forensics labs utilize cutting edge techniques such as DNA fingerprinting, forensic entomology, and trace chemical analysis. While these procedures use state-of-the-art technology, many crimes are still solved by using classical techniques to examine the physical evidence at a crime scene.

The Evolution of Electrophoresis
Agarose gel electrophoresis is a biotechnology technique used to separate DNA molecules according to their size. The mixture of molecules is added into depressions (or “wells”) within a gel, and then an electrical current is passed through the gel. Because the sugar-phosphate backbone of DNA has a strong negative charge, the current drives the DNA through the gel towards the positive electrode.
