Figure 8. δ/ω-PLTX-Pt1a reduces stimulus-induced intracellular Ca²⁺ rise in cultured Drosophila neurons.

Summary of average decreases in high K⁺ induced intracellular Ca²⁺ rises produced by δ/ω-PLTX-Pt1a and ω-PLTX-Pt1a (PLTX II). 20 nM δ/ω-PLTX-Pt1a blocked a portion of stimulus-induced intracellular Ca²⁺ rises, while 5 nM ω-PLTX-Pt1a nearly blocked all the Ca²⁺ rises in cultured Drosophila embryonic neurons. Values are shown as mean ± S.E.
