A simple and reliable method for the purification of human alphafetoprotein (AFP) from amniotic fluid and fetal livers.


Highly purified human alphafetoprotein has been isolated from amniotic fluid and fetal livers by a combination of salting-out, and gel filtration, ion exchange, and concanavalin-A affinity chromatography. They yield ranged from 25 to 37%, and purity was demonstrated by radioimmunodiffusion, crossed radioimmunoelectrophoresis, polyacrylamide gel… (More)
