saturation analysis of anterior pituitary tissues from monkeys receiving various treatments revealed an apparent mean dissociation constant ( kd ) of 0.53 +/- 0.17 ( +/- se ) x 10 ( -10 ) mol/l ( n = 3 ) for [ 3h ] r1881 ( androgen ) binding to cytosol , 2.6 +/- 0.50 x 10 ( -10 ) mol/l ( n = 3 ) for [ 3h ] r2858 ( estrogen ) binding to cytosol , 1.7 x 10 ( -10 ) mol/l ( n = 2 ) for [ 3h ] r5020 ( progestin ) binding to cytosol , and 6.2 x 10 ( -10 ) mol/l ( n = 2 ) for [ 3h ) r1881 binding to cell nuclear extract .
