However, once an actual experiment has been initiated, the state of phenol red in the media is typically no longer utilized, particularly with image-based proliferation assays. This 30 ml bottle of phenol red is a pH indicator; it turns yellow below 6.8 pH and bright fuschia (pink) above 8.2 pH. A solution of phenol red will have a yellow color at a pH of 6.4 or below and a red color at a pH of 8.2 and above. This dye has long been used to quickly assess the status of bulk cultures being propagated for subsequent experimental analysis. Aqueous solutions of phenol are weakly acidic and turn blue litmus slightly to red. In fact, most of the molecule is identical, except for a small group that dangles off the side of the main structure.

In crystalline form, and in solution under very ac… As both the size and the number of drops have a decisive effect on the resultant colour complex, the reagents need to be added with a high degree of precision. Phenol Red is used as a pH indicator in cell culture applications. Do not shake forcefully to avoid foaming. Phenol red is the acid-base indicator in the media. Recall that an acid- base indicator is a substance whose color in solution is dependent on the pH of the solution it is dissolved in. In order to give you a better service Tintometer uses cookies. Phenol red can be used to measure hydrogen peroxide in cultured macrophages in multiwell plates. A pH indicator changing colour from yellow below pH 6.8 to bright pink above pH 8.2, it is commonly used as an indicator in cell cultures and in … For the best experience on our site, be sure to turn on Javascript in your browser. Phenol red can be used to measure hydrogen peroxide in cultured macrophages in multiwell plates. Most microorganisms convert glucose to pyruvate during glycolysis; however, some organisms use alternate pathways. A solution of phenol red is used as a pH indicator: its color exhibits a gradual transition from yellow to red over the pH range 6.6 to 8.0. 110987 View Pricing & Availability.
