title: Prolactin receptors in estrogen receptor-deficient mammary carcinoma.
abstract: We demonstrate for the first time the presence of specific high-affinity receptors for prolactin in rat mammayy carcinoma. There appear to be no significant differences between normal rat mammary tissue and the transplantable, estrogen receptor-deficient R3230AC tumor with regard to the number of binding sites, the affinity of the receptor for prolactin, or the specificity of binding.
