Figure 2: Relative quantitative analysis of each glycan. Hexose-type glycan (A), High-mannose-type glycan (B), NeuAc-type glycan (C), NeuAc-type glycan (D). High-mannose-type glycan and NeuAc-type glycan displayed progressive enhancement through the estrous cycle. However, expression of sialylated NeuGc-type glycan was remarkably promoted only during the ovulation phase. Error bars represent SD. Significance relative to ovulation phase (vs. early follicular phase, middle follicular phase, and luteinization follicular phase; *P< 0.05, vs. control phase; *P<0.01).
