Biotechnology Basics: Dye Electrophoresis

Agarose gel electrophoresis is an essential biotechnology technique used in research, clinical, and teaching labs across the world every day.  Electrophoresis uses electricity and a porous gel matrix to separate different molecules – dyes, nucleic acid, proteins – into discrete…

Resources to teach your students about chemical safety using Safety Data Sheets

Student experimentation in the laboratory is an integral part of the biotechnology education. However, there are hazards in the lab, and when protocols are not followed, accidents can happen. Therefore, laboratory safety is a critical part of scientific training. This…

Biotechnology Basics: Chromatography

What is chromatography? Chromatography is the separation of molecules based on their physical properties by passing a fluid sample through a solid, stationary matrix.  The interactions between the sample and the matrix influence the way the molecules flow through the…
