The peptides derived from egg white proteins were fractionated on Sephadex G-25 gel filtration column and the fraction with the highest DPPH· radical scavenging activity was purified on Sephadex G-15 gel filtration column.

Enhancement immune function of ovalbumin peptide in mice;

The thermal denaturation of chicken ovalbumin were investigation by differential scanning calorimetry(DSC).

To determine the core promoter of chicken ovalbumin gene and 5′upstream regions,the transcription initiation site of ovalbumin gene was confirmed by 5′RACE method,at the same time,the regulatory elements of chicken ovalbumin gene were determined by sequence analysis.

Characterization of binding property to hCG receptor and inhibition effect of ovalbumin glycopeptides;

Based on numerous references on insect yolk proteins, molecular characterizations of vitellogenins (Vgs) , vitellins (Vis) or yolk polypeptides (YPs) from more than 60 species of 11 orders in Insecta were summarized and compared.
