Calcium Indicators

Browse reagents with product-specific evidence for calcium detection, measurement or staining. The selection includes different reporting formats; consult each product for its intended use and experimental conditions.

Calcium-sensitive fluorescent indicators and calcium-detection or staining reagents are not interchangeable. This page does not imply that every product measures free intracellular calcium. Indicator precursors, calcium-channel pharmacology and probes made by subsequent conjugation are outside this selection without evidence for the exact reagent.

    Calcein sodium salt

    Calcein sodium salt is a fluorescent dye that serves as a self-quenching probe, primarily utilized for assessing lipid vesicle leakage. It acts as a complexometric indicator for titrating calcium ions with EDTA and can be employed in the fluorometric determination of calcium concentration. Unlike its cell-permeable counterpart, Calcein-AM, Calcein itself does not penetrate intact cell membranes, making it suitable for in vitro studies. Additionally, it is useful as a model compound for evaluating the efficiency and bioavailability of drug delivery systems.
