EGTA activates CRAC current via passive ER Ca2+ depletion in HEK293 cells co-expressing YFP-STIM1 and Orai1-CFP..
By Anonymous on 12/16/2018
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: HEK293

ER Ca2+ in HEK293 cells co-expressing YFP-STIM1 and Orai1-CFP was passively depleted with pipette solution, containing (in mM): 20 EGTA, 145 Cs-methanesulfonate, 8 NaCl, 5 MgCl2 and 10 HEPES, pH 7.2 with KOH.

EGTA inhibits 15d-PGJ2 induced TNFa production by cardiomyocytes.
By Anonymous on 12/10/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: cardiomyocytes

HL-1 cells were incubated with EGTA (5 mM) for 30 min prior to 15d-PGJ2 (15 µM) treatment for 4 h to follow TNFa concentrations in the cell culture medium. Addition of EGTA resulted in abolition of 15d-PGJ2 induced TNFa production.
