  • 功能:
    This is a non-secretory ribonuclease. It is a pyrimidine specific nuclease with a slight preference for U. Cytotoxin and helminthotoxin. Selectively chemotactic for dendritic cells. Possesses a wide variety of biological activities.

In healthy children, 95th Percentile values ranged from 1519 mg/kg at 0 months to 54.4 mg/kg at 144 months for fecal calprotectin (fCP) and from 9.9 mg/kg at 0 months to 0.2 mg/kg at 144 months for fecal eosinophil-derived neurotoxin (fEDN).
