Abstract: | alpha 1-Acid glycoprotein could be isolated by a one-step extraction method from human sera and plasma. Protein recovered in the water phase after extraction with phenol at 70 degrees C for 20 min was verified as human alpha 1-acid glycoprotein when it was compared with the reference standard human alpha 1-acid glycoprotein by Ouchterlony double immunodiffusion, sodium dodecylsulfate-polyacrylamide gel electrophoresis, Western blot analysis, and periodic acid-Schiff stain. The present isolation procedure is simple and fast, and can extract about 81% of the total alpha 1-acid glycoprotein in the sera and plasma, as determined by radial immunodiffusion. |
