Abstract:
This paper described the results of the optimal method for preparation and extraction of lectin from Phaeoporus obliquus(Pers ex Fr).(J.Schroet).We determined the optimal buffer solution using the ag-glutination test with 2% hare blood cells.The optimal extraction process included the following parameters that were conformed by optimization analysis: material-water ratio,extraction time,concentration of sodium chloride and the pH value.The results are that the agglutination indexes of POL using TBS and PBS extrac-tion buffer were 64 and 16,respectively.The optimal extraction process is that,the material-water ratio was 1:50,the extraction time was 20 h,while the concentration of sodium chloride was 0 mol/L and pH was 8.0.The agglutinability of POL was 256 examined by this method.The optimized extraction process is stable and practicable,which may supply some basis for the application of the lectin from Phaeoporus obliquus in immunoregulation.
