| Uses | PhenolRed Sodium Salt is a water soluble pH indicator commonly employed in cell biology laboratories as a cell tissue culture pH marker. PhenolRed sodium salt is a water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range. It is commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenolred added to the growth medium will have a pink-red color. Usually 15 mg/l is used to produce this effect. If problems arise, such as dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, PhenolRed could potentially be useful as a differentiation factor. It can also be used as reactant/reag |
| Uses | PhenolRed sodium salt has been used as an indicator during single-guide RNA microinjection into one-cell stage zebrafish embryos. |
| General Description | PhenolRed sodium salt is widely used as a pH indicator. At a pH of 6.4 and below, phenolred solution will have a yellow color. At a pH of 8.2 and above, it will have a red color. It is commonly used in culture media to detect neutral to acidic pH changes. |
