Biological Activity
Fura-2 itself cannot pass through the cell membrane, and various methods (such as microinjection, ATP permeabilization, scrape loading, and pH shock) can be employed to insert Fura-2 into the cytoplasm of cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
