[The hydrophobic properties of beta-glycoprotein from the blood serum of pregnant rats]

Abstract

During immunoelectrophoresis in the presence of tween-80, triton X-100 and ammonium sulfate blood serum beta-glycoprotein of pregnant rats migrated along with beta-globulins as a main single band; its minor components in zones of alpha- and gamma-globulins were not detected. beta-glycoprotein was completely absorbed by phenyl sepharose in the absence of ligand as well as when the spacer arm for phenyl group was short. When the phenyl group was linked with the template through a long spacer arm, three froms of beta-glycoprotein with different immunoelectrophoretic mobility were detected after absorbtion with phenyl sepharose. Hence, beta-glycoprotein is hydrophobic and is represented by alpha-, beta- and gamma-forms in blood plasma of pregnant rats.
