Different Methods for Cell Viability and Proliferation Assay: Essential Tools in Pharmaceutical Studies

Area of Science:

• Biomedical Sciences
• Cell Biology
• Pharmacology

Background:

• Cell viability assays are essential for assessing live cells versus total cells, critical in cell culture and drug screening.
• These assays are fundamental for evaluating cell survival and optimizing experimental conditions after compound treatment.
• Measuring cell viability is often the primary goal in pharmaceutical research, particularly for determining agent toxicity.

Purpose of the Study:

• To review and analyze existing literature on cell viability assays.
• To highlight the importance of cell viability assessment in various biological and pharmaceutical research contexts.

Main Methods:

• A comprehensive literature search was performed using MEDLINE (PubMed), Web of Science, and Scopus databases.
• The research focused on identifying and evaluating different cell viability assay methodologies.

Main Results:

• A diverse array of cell viability assays exists, with method selection influenced by factors like cost, speed, and complexity.
• No single assay is universally perfect; each possesses distinct advantages and disadvantages.

Conclusions:

• Utilizing at least two complementary cell viability assays can mitigate individual method limitations.
• This dual-assay strategy, measuring parameters like metabolic health and cell permeability, enhances confidence in reporting therapeutic agent efficacy and toxicity.
• Researchers can more reliably determine effective doses and understand treatment impacts on different cell types by employing multiple assays.
