title: [Two-step purification of estradiol calf uterine cytosol receptor].
abstract: The use of two affinity chromatography methods: heparin-Ultrogel and estradiol 7 alpha-(CH2)3-poly (alanine-lysine)-agarose, allows us to purify the calf uterine estradiol cytosol receptor with a 20% recovery. Electrophoresis under denaturing conditions allows us to estimate its molecular weight as 70 000 dalton.
