Figure 9. Effect of Ca²⁺-free media on kaempferol-induced Ca²⁺ waves.

A typical line-scan image showing the effect of kaempferol before and during exposure to Ca²⁺-free media is shown in A. An intensity profile plot of this record is plotted in B and a summary plot of the mean amplitude (ΔF/F₀) of the initial kaempferol-induced Ca²⁺ transient in the absence and presence of Ca²⁺-free media is shown in C.
