| Abstract: | OBJECTIVE To study preparation method and to test biological activity of sheep placenta peptide. METHODS Dialysis method and ultra filter method were used to abstract sheep placenta peptide. T lymphocyte transformation test was used to assess the biological activity of sheep placenta peptide. RESULTS The sheep placenta peptide was a set of small chain polypeptides. T Lymphocyte transformation rate by ultra filter method was high than that by dialysis method. CONCLUSION The polypeptides and biological activity of sheep placenta peptide repared by ultra filter method were superior to those of dialysis method. |
