Fura-2 AM (solution)
Based on 1 Customer Validation
Fura-2 AM (solution) (Fura-2 Acetoxymethyl ester (solution)) is a membrane permeable, intracellular, UV light-excitable and ratiometric fluorescent Ca2+ (calcium ion) indicator. Fura-2 AM crosses cell membranes and is converted to Fura-2 (HY-D0110A) via cellular esterases. Fura-2 AM can be used to detect calcium in cells.

Guide (The following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Fura-2 AM diffuses across the cell membrane and is de-esterified by intracellular esterases to generate free Fura-2 acid.
1. Aliquot 2 mL of culture medium into a conical tube and warm it to 37°C. Add 2 μL of Fura-2 AM stock solution to prepare a 1 μM Fura-2 AM solution. Vortex vigorously for 1 min.
2. Transfer the loading solution into a tissue culture dish, and move the cell-containing coverslip into the dish.
3. Incubate neurons at 37°C in a dark incubator for 30 min. Accurately record the incubation time.
4. Prepare a new culture dish containing 2 mL tissue culture medium without Fura-2 AM. Remove the coverslip from the loading solution and transfer it into the new dish.
5. Mount the coverslip onto the imaging chamber.

Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.
