| Product Name | Sodium Ion Fluorescent Probe 520 (AM, Cell Permeant) |
| Catalog No. | RESK-0562 |
| Description | Sodium Ion Fluorescent Probe 520 (AM, Cell Permeant) is a cell membrane-permeant fluorescent probe designed for monitoring sodium ions (Na+) in living cells. As a Na+-specific fluorescent indicator, it enables accurate measurement of sodium ion concentrations in biological samples. Upon binding to Na+, the probe exhibits a substantial increase in fluorescence intensity. By measuring the fluorescence emission intensity, researchers can evaluate sodium ion levels in biological samples or investigate Na+ dynamics induced by biological stimuli. |
| Intended Use | For monitoring intracellular sodium ion (Na+) levels and Na+ dynamics in living cells and biological samples. |
| Principle / Technology | The AM ester form is cell permeant and enters living cells. When the indicator binds Na+, its fluorescence intensity increases markedly, allowing Na+ levels to be assessed by measuring fluorescence emission (Ex/Em 490/525 nm). |
| Detection Method | Fluorescence measurement at Ex/Em 490/525 nm. |
| Sample Type | Living cells; biological samples. |
| Performance Range / Specifications | Appearance: powder Ex/Em: 490/525 nm Solubility: soluble in DMSO Molecular weight: 804.8 |
| Specificity | Na+-specific fluorescent indicator; fluorescence intensity increases substantially upon binding to sodium ions. |
| Components / Formulation | Single-component reagent supplied as a powder. |
