What is a hemacytometer?
A hemacytometer is a specialized microscope slide used for counting cells in a given volume.
How do you prepare a hemacytometer?
Clean the surface and cover slip with 70% ethanol before use.
What is the purpose of the Trypan Blue Viability Assay?
It is used to distinguish between viable and non-viable cells in a culture.
Why is cell counting important?
Accurate cell counting is crucial for standardizing culture conditions and ensuring experimental reliability.
What does cell concentration refer to?
Cell concentration refers to the number of cells present in a specific volume of suspension.
How can you assess cell viability?
Cell viability can be assessed using dyes like Trypan Blue, which stain non-viable cells.
