Various assays are employed to measure cell viability, each with its own advantages and limitations. Commonly used methods include the MTT assay, which measures metabolic activity, the Trypan Blue exclusion test, which assesses membrane integrity, and the lactate dehydrogenase (LDH) assay, which detects cell leakage. Each of these assays offers a different perspective on cell health, allowing researchers to choose the most suitable method based on their specific requirements.
