The method of separation and identification of the glycoprotein in Hevea brasiliensis latex is described in this article. The fractional precipitation of F serum (frozen serum) was realized with ammonium sulphate and the precipitate was desalted by dialysis or with Sephadex G-25. When the protein solution obtained was subjected to the electrophoresis on the polyacrylamide gel, three protein bands were recognized. If the above-mentioned protein solution was ultrafiltrated with an ultrafiltering membrane having a molecular weight cut-off value of about 11,700 daltons (the molecular weight of cytochrome C), the filtrate showed only one protein band after being examined with the electrophoresis on the polyacrylamide gel. It was identified as a kind of glycoprotein by the specific color-producing reaction. If the F serum was directly separated on Sephadex G-25 column and the protein fraction obtained was ultrafiltrated with the same method as mentioned above, it could be found that this filtrate was a kind of glycoprotein.
