assays for cell viability

Assays for cell viability are tests used to determine if cells are alive and healthy. They typically measure how well cells can perform functions like producing energy or maintaining membranes. Common methods include color-changing dyes that live cells can convert into visible colors, or assays that detect enzymes only active in living cells. These tests help researchers evaluate the impact of drugs, treatments, or conditions on cell health, providing critical information on cell survival and overall function in a straightforward, quantifiable way.
