DescriptionBrominated fluoroscein dye derivative used as an acidic red stain for cell cytoplasm.
- Acid Red 87
- Bromo acid J
A red fluorescent dye from the xanthene family used as an acidic red stain for cell cytoplasm. Reduces the affinity of Mg2+-ATPase for ATP and increases the enzyme affinity for Mg2+ at concentrations of 10-50 μM. At higher concentrations near 100 μM the affinity for Mg2+-ATPase for the ion-activator has been shown to be reduced.
Storage instructionsStore at Room Temperature. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in ethanol to 1 mg/ml
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
