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).

GFP is a common marker for transfection in biological systems. In order to assess transfection success it is important to optimize cell counting settings. this technical note provides a detailed protocol for optimizing the CellDrop GFP Count App.

EasyApps software includes pre-installed count apps for rapid counting and viability assessment. This note defines the count settings and how each can be adjusted to optimize performance.

The presence of debris, non-nucleated cells and highly variable cell numbers can make counting primary cells challenging. Peripheral Blood Mononuclear Cells (PBMCs) are a common primary cell source where accurate enumeration is essential. This technical note outlines the best practices for counting PBMCs using the CellDrop Automated Cell Counter.

The Trypan Blue app on CellDrop™ Series instruments enables rapid automated cell counting and viability of cell suspensions stained with Trypan Blue.
