Indo-1, Pentasodium Salt Fluorescent Calcium Indicator
Our Indo-1 Pentasodium Salt is a fluorescent calcium indicator that can be loaded into cells via microinjection or scrape loading. Calcium imaging is widely used to measure neuronal activity.
Product Specifications
Background
Indo-1, pentasodium salt is a membrane-impermeant calcium indicator that can be loaded into cells via microinjection or scrape loading. As the indicator does not covalently bind to cellular components, it may be actively effluxed from the cell by organic anion transporters. The rate of efflux increases with temperature, and may vary between cell types, resulting in variable retention times of a few minutes to hours. Experiments using indicators in cells usually are performed within one or two hours of loading, but it may be possible to re-load cells with indicator if needed.
