Figure 2From: Progesterone-induced changes in the phosphoryl potential during the meiotic divisions in amphibian oocytes: Role of Na/K-ATPase31P-NMR spectra of 200-250 Rana pipiens follicles in meiotic prophase-arrest obtained with (lower) and without (upper) the use of convolution difference to minimize the broad phosphoprotein signal. Sampling time was 40 min; follicles were superfused with Ringer's solution at 1 ml/min as illustrated in Figure 8.Back to article page
