Abstract
This protocol describes a method to perform calcium imaging with Fura-2 (live-cell imaging)
Cells are washed with HBSS (Cat No. 14025092, ThermofisherScientific)
Cells are loaded with 5uM of Fura 2-AM (F1221, ThermofisherScientific) in HBSS.
Note
Fura 2-AM: 340/380 ratiometric measurement. Upon binding calcium, Fura-2 exhibits 340 nm and does 380 nm in the rest of the condition.
CCD protocol is set up by selecting a501 nm wheel (both 340 nm and 380 nm wavelength are excited b 501 nm).
