Phenol red solution (liquid, 0.5%, sterile-filtered) is widely utilized in research focused on:

• pH Indicator: Commonly used in cell culture and microbiology, it serves as a reliable pH indicator, changing color in response to shifts in acidity or alkalinity, helping researchers monitor culture conditions effectively.
• Cell Viability Assays: Employed in various assays to assess cell health and viability, it provides a visual cue for researchers to evaluate the effects of drugs or treatments on cell populations.
• Diagnostic Applications: Utilized in clinical laboratories for testing and diagnostics, particularly in urine tests, where it helps indicate the pH level, aiding in the diagnosis of various conditions.
• Biochemical Research: Acts as a vital component in biochemical experiments, allowing scientists to study enzyme activities and metabolic processes under controlled pH conditions.
• Educational Purposes: Frequently used in educational settings for teaching purposes, it helps students understand concepts of pH and cellular processes through hands-on experiments.
