GLU-ANN was founded for preparing the target pollock hydrolysates (PFH).
PFH enhances the humoral immunity, cellular immunity and non-specific immune function.
Mechanism of PFH is through direct up-regulation of IL-2 IL-4 and IL-6 gene expression.
The active central fragment was purified and identified as PTGADY.
PFH can act as a potent immunomodulator.
