摘要: Abstract Specific receptors of 3 H-estradiol-17β were demonstrated by a sucrose gradient assay cytosols from the lactating mammary gland and R3230AC adenocarcinoma rat. These estrogen receptors, each which sedimented at approximately 8S, exhibited similar dissociation constants (K d ∼1×10 −9 M) steroid binding specificities. Ovariectomy host had no apparent effect on number sites/mg protein in tumor.
