works well in motor neurons
By Karthik krishnamurthy on 10/24/2018
Assay Type: In Vitro
Species: Rat
Cell Line/Tissue: motor neurons

Used for imaging calcium entry in motor neurons at 1 mM concentration

motor neurons loaded with 1 mM concentration of fluo4-am loaded at 37 degrees for 15 minutes in aCSF. After 15 minutes cells were gently washed with aCSF twice and left in dark for 10 minutes for complete de-esterification of the dye.
