[Reversible precipitation of the glucocorticoid receptor from rat liver by La3+ ions].

It was shown that La3+ ions are capable of precipitating the glucocorticoid receptor from rat liver. Treatment of cytosol containing either free receptor or the hormonereceptor complex with 0,005 M La(NO3)3 results in recptor precipitation. The pellet is readily dissolved in buffer with EDTA.
