In the intricate world of cell biology and biotechnology, maintaining optimal conditions for cell growth is paramount. Phenol Red Sodium Salt, identified by its CAS number 34487-61-1, plays a crucial role in achieving this by acting as a visual pH indicator within cell culture media. Its consistent presence in many basal media formulations highlights its importance for researchers aiming to support the health and viability of their cell lines.

The primary function of Phenol Red Sodium Salt in cell culture is to provide an immediate visual cue about the pH status of the culture medium. As cells metabolize nutrients and produce waste products, the pH of the medium can fluctuate. Phenol Red Sodium Salt, with its characteristic color transitions, allows scientists to easily monitor these changes. Typically, a healthy cell culture medium containing Phenol Red Sodium Salt will appear red. If the pH drops into the acidic range (below pH 6.8), the indicator turns yellow, often signaling increased metabolic activity, nutrient depletion, or potential bacterial contamination. Conversely, a shift towards purple or magenta (above pH 8.2) might indicate alkaline conditions, which can be caused by excessive CO2 loss or contamination with alkaline substances.

This visual feedback system is invaluable for managing cell cultures efficiently. It allows researchers to determine when media replenishment is necessary, thereby preventing suboptimal growth conditions that could compromise experimental results. For those looking to buy Phenol Red Sodium Salt for their cell culture needs, sourcing from reliable chemical suppliers in China ensures the purity and consistency required for sensitive biological applications. The compound’s role as a chemical reagent in this context is indispensable.

While Phenol Red Sodium Salt is widely used, it's important for researchers to be aware of its potential limitations. In certain hormone-sensitive studies, its weak estrogenic activity might interfere with results. In such cases, phenol red-free media are available. However, for general cell viability monitoring and routine culture maintenance, Phenol Red Sodium Salt remains a highly effective and cost-efficient choice. Its availability as an intermediate for organic synthesis also means that its production is well-established, contributing to its accessibility.

The reliability of Phenol Red Sodium Salt makes it a cornerstone for various research areas, from basic cell biology to drug discovery and development. Its contribution to maintaining a stable cellular environment indirectly supports advances in areas where cell cultures are vital. As a key component supplied by chemical manufacturers, it underpins much of the progress made in laboratories worldwide.

In conclusion, Phenol Red Sodium Salt (CAS 34487-61-1) is more than just a dye; it is an essential tool in cell culture. Its ability to provide a simple, visual indication of pH changes helps researchers maintain optimal conditions for cell growth and experiment integrity. For any laboratory working with cell cultures, understanding and utilizing this critical chemical reagent is key to success.
