Fura-2 AM (Cell permeant) is a high affinity, cell permeable calcium indicator which is ratiometric and UV light excitable. AM ester derivative of Fura-2.
Fura-2 AM (Cell permeant) can noninvasively be loaded into live cells by incubation and is widely used for ratio-imaging microscopy and measuring intracellular calcium elevations in neurons and other excitable cells.
Excitation 340/380nm, Emission 505nm.
Purity
>95%
Customer comments
Reliable product - product worked well for live cell calcium imaging in multiple cell types i.e. primary hippocampal neurons and HEK293 kidney cells. Verified customer, University College Dublin
Reliable - I have tried Fura-2 AM across multiple cell types and in different assays. Works well and is reliable. Verified customer, UEA: University of East Anglia

Figure 1. Fura-2 displays a shift in F340/F380 ratio in response to increased intracellular Ca2+.
500nM ionomycin (HB1002) was applied to HEK293 cells preincubated with Fura-2 AM after a baseline period. Ionomycin leads to increased intracellular Ca2+ therefore increases that 340nm signal associated with bound Ca2+ and decreases the 380nm associated with unbound Ca2+. This is displayed as a large increase in F340/F380 ratio which is a much more robust readout. For more details please see our Fura-2 protocol.
Figure 2. Ionomycin increases intracellular Ca2+ as measured by an increased F340/F380nm ratio.
500nM ionomycin (HB1002) was applied to HEK293 cells preincubated with Fura-2 AM leading to increased intracellular Ca2+ and therefore an increased F340/F380 ratio. For more details please see our Fura-2 protocol.
Figure 3. Carbachol stimulation of M3 receptors in HEK293 cells leads to Ca2+ release in a dose dependent manner.
Carbachol acts upon the Gq coupled muscarinic M3 receptors endogenously expressed in HEK293 cells to cause endoplasmic reticulum Ca2+ release which is detected using Fura-2 as a change in the ratio of fluorescence at 340 and 380nm. For more details please see our Fura-2 protocol.
