Figure 4From: Modulation of intracellular calcium and proliferative activity of invertebrate and vertebrate cells by ethyleneChanges of [Ca2+] i level in SaOS-2 cells kept under pressure (1 atm) following ethylene gas exposure. Ethylene gas was injected into the pressure chamber 5 min after starting fluorescence measurements (arrow). The values for the ratios of the 340/380 nm images are shown. The results are expressed as mean values ± S.E.; n = 20.Back to article page
