Heterogeneity of molybdate-stabilized, nontransformed glucocorticoid receptor from rat liver

Nontransformed glucocorticoid receptor stabilized with sodium molybdate exists as the heterogeneous forms which have slight differences in net charges and sedimentation coefficients. These differences could be detected by sequential analyses with DEAE-Sephacel chromatography and glycerol gradient centrifugation. The heterogeneity in the nontransformed receptor appears to be caused by the association of an acidic component(s) with the transformed receptor.
