pubmed:abstractText |
Nuclei from rat ventral prostate were disrupted by sonication and treated with micrococcal nuclease to precipitate nuclear proteins including the androgen receptor. The precipitate was dissolved in 0.6--1.2 M ammonium bicarbonate buffer, pH 7.6, with no loss of receptor when compared to the conventional Tes buffer, pH 7.0 containing 0.6--1.2 M NaCl. Lyophilisation of the solubilised protein did not produce any qualitative or quantitative differences in the recovery of receptor relative to a non-lyophilised control preparation, both of which were analysed for binding properties by Sephadex G-25/G-100 dual-column chromatography. Over longer periods of storage at -80 degrees C, the rate of inactivation of receptor was found to be 6% per week. The stability of the lyophilised receptor was improved by the inclusion of MgCl2 and SH-reducing agents in the ammonium bicarbonate buffer. Recovery improved also with increasing ionic strength of the buffer used to dissolve the lyophilised receptor.
