Phenol red is also known as phenolsulfonphthalein or PSP. This synthetic dye is commonly used as a pH indicator, as it changes color depending on the pH of the solution it is in. The color transition is quite noticeable at this concentration, shifting from yellow in acidic conditions to red in neutral, and finally to pink/fuchsia in basic conditions. When present at a 0.1% concentration, phenol red takes the form of a red liquid in solutions that are neutral to slightly basic. It is typically dissolved in water and utilized in various scientific and industrial settings to monitor pH levels. The 0.1% solution of phenol red is particularly beneficial in applications that require a higher sensitivity to pH changes.

Application :

• In cell culture media, phenol red at 0.1% is used to monitor pH changes. This higher concentration allows for more sensitive detection of pH fluctuations, helping to maintain optimal conditions for cell growth and metabolism.
• In microbiological media, phenol red helps differentiate bacterial species based on their metabolic byproducts, which alter the pH of the medium.
• This concentration is ideal for various biochemical assays that require precise pH monitoring, such as enzyme kinetics studies where pH can significantly affect enzyme activity.

Benefits :

• Provides enhanced sensitivity to pH changes
• Distinct color change
• Inexpensive and readily available
