Fungi - Living Material

Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.

Saccharomyces cereviciae Strains for Genetic Manipulation

Saccharomyces cereviciae Strains for Genetic Manipulation

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.
