Counting cells in hemocytometer
WebJan 29, 2024 · The way you do this is by counting live and dead cells using a hemocytometer, and adding a dye that will selectively penetrate inside the dead (or apoptotic) cells, whose cellular membrane is damaged, while live cells will stay unstained. WebA hemocytometer, also known as a counting chamber, is a microscope slide with an engraved gridded area used for counting different types of cells. There are many types of hemocytometers, each with its own specificities, but the most commonly used are the Neubauer (Thoma) Chamber and the Neubauer Improved Chamber.
