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.
Understanding DNA Sequencing, Part II
DNA sequencing in today’s laboratory is a little different than it was when it was developed in the late 1970’s. Historically, a single sequencing gel contains 48 sample wells, meaning that we could run 12 complete sequencing reactions at one time. This was instrumental for sequencing single genes, but it was not ideal for massive sequencing efforts.

Waste not, want not — a fun science experiment using leftover FlashBlue™!
Agarose gel electrophoresis is used to separate DNA fragments in complex mixtures according to their size. However, because DNA is clear and colorless, these bands cannot be seen with the naked eye. Edvotek® offers several different methods for visualizing the DNA separated by electrophoresis

Understanding DNA Sequencing, Part I
The basic unit of all living organisms, from bacteria to humans, is the cell. Contained within the nucleus of these cells is a molecule called deoxyribonucleic acid (or DNA). Today, we know that DNA is the blueprint used to build an organism – our genetic makeup, or genotype, controls our phenotype (observable characteristics). The directions coded for by our genes controls everything from growth and development to cell specification, neuronal function, and metabolism.

Demystifying the NGSS High School Life Science Core Ideas
The Next Generation Science Standards are a set of education standards that focus on preparing students for careers in science including engineering and technology. These new set of standards were set in place to emphasize areas in science fundamental to all of biology – Life Science, Physical Science, and Engineering and Design. Today we will focus on the core ideas of Life Sciences in detail as well as discuss experiments that fall into each different category.

Back to School for 2014-15!
Can you believe it? We’re already at the end of our summer vacation. I’m sure that you are busy getting your classroom ready for the first day of school. We’ve had a really busy summer as well, designing new experiments and equipment to be used in your classroom laboratory.
