Fig. 6. Simultaneous measurements of cADPR change with the cGMP and IP₃ changes in eggs after insemination. Two representative data from three experiments on A. crassispina (A,B) and two from four experiments on H. pulcherrimus (C,D) are shown. cGMP (red), cADPR (green) and IP₃ (blue) at each sampling point were measured on the same aliquot of egg suspension. Scales for cGMP and cADPR are on the left axis in each panel and scales for InsP₃ are on the right axis.
