Quantitative Stoichiometry

Distinguish between endospores and the vegetative structures of bacterial cells. The endospores will stain green against a pink background. Includes spore staining solution, safranin O solution, and instructions.
Shelf life is 3 years.

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

High quality microbiological media at an economical price.

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins
