The Yeast app on CellDrop Series instruments enables rapid automated cell counting for live/dead yeast cell suspensions.
Many yeast samples from brewing contain extracellular debris and are small in size, making them difficult to count using a traditional hemocytometer or brightfield cell counter. This technical note will provide the information needed to accurately count yeast concentration and viability using the fluorescent dyes fluorescein diacetate (FDA) and propidium iodide (PI).
Viability is a key metric in determining the activity or metabolism of yeast cells in solution. It i...
