Macrophages were incubated with different concentrations of [3H]-5αDHT in the presence or absence of a 100 fold excess of unlabelled 5α-DHT. Labelled cells were separated from unbound steroid by immunomagnetic beads coated with anti-rat macrophage antibody. The binding identified in the rat macrophages was highly selective towards androgenic compounds. The dissociation constant (kd) value for the receptor was calculated to be 3.3X10-9M and 5X10-9M for macrophages of male and female rat respectively. The number of receptors in each cell was 792±3 and 120±1 for male and female respectively.
