Table II. Proteins differentially abundant between estrus and luteal phase in the uterine fluid. Proteins more abundant in estrus and luteal phase: list of the 20 quantitatively main proteins based on spectral counting quantitative method at estrus and luteal phase. Estrus: NSC (normalized spectral counts) at estrus. Luteal phase: NSC during luteal phase. O/LP ratio: oestrus/luteal phase ratio of NSC.
