Abstract: | Using gel electrophoresis and autoradiography, we have shown that plamitic, stearic, oleic and arachidonic acids as well as tryptophan bind to alpha-fetoprotein derived from fetal swine serum. It is also shown that these ligands bind to albumin from both fetal and adult swine serum. The results suggest that alpha-fetoprotein in the fetus has transport functions similar to albumin in the adult. |
