Figure 4From: Proteomic characterization and evolutionary analyses of zona pellucida domain-containing proteins in the egg coat of the cephalochordate, Branchiostoma belcheriThe expression profile of amphioxus ZP proteins determined by real-time qPCR of RNA from eight tissues of adult B. belcheri. The Y-axis denotes the ratio of ZP proteins to β-actin. The scales of the vertical bars of the two panels are different, and the top panel scale is 100 times greater.Back to article page
