Solubilization and Purification of a Prolactin Receptor from the Rabbit Mammary Gland
[ PUBLICATION ]
A receptor for prolactin and other lactogenic hormones (human growth hormone and placental lactogens) has been solubilized by 1% (v/v) Triton X-100 from a crude particulate membrane fraction isolated from pregnant rabbit mammary glands. The receptor remained in solution after centrifugation at 200,000 x g for 2 hours. Triton X-100 at concentrations higher than 0.01% (v/v) affected the physical properties of 125I-prolactin, whereas 125I-human growth hormone (hGH) was unaffected and, ...

Extract: Serum prolactin (HPr) and serum growth hormone (HGH) were determined by double antibody radioimmunoassay methods. Markedly elevated levels of serum prolactin with considerable variation were observed in the neonatal period. No significant difference was observed in six matched arteriovenous cord blood samples. No sex difference was noted in the full term infants, whereas the mean value for 24 premature male infants in the 1st week of life (190 ± 17 ng/ml sem) was significantly ...

Receptors for human, simian, ovine, bovine and murine prolactin, human growth hormone and human placental lactogen have been identified in plasma-membrane-containing subcellular particles isolated from rabbit mammary glands. The association and dissociation of (125)I-labelled prolactin are time- and temperature-dependent processes, both being maximal at 37 degrees C. (125)I-labelled prolactin prepared by the enzymic iodination procedure with lactoperoxidase binds better to receptors than ...

Factors influencing the secretion of human prolactin and growth hormone in menstrual and gestational women
[ PUBLICATION ]
Human pituitary prolactin (PRL) is released in a pattern that is different from growth hormone (HGH). Basal PRL concentrations remain unchanged throughout the menstrual cycle and bear no apparent relationship to the cyclic change in gonadotropins. Significant increases in PRL occur after intramuscular chlorpromazine (CPZ). The response is dose related. These results correlate with PRL values measured in patients ingesting large amounts of phenothiazines for psychiatric disease. ...

A radioimmunoassay for primate prolactin has been developed, with [(131)I] monkey prolactin, and antibodies to monkey or human prolactin. The assay is specific for prolactin; human growth hormone, and human and monkey placental lactogen show no significant crossreaction. The assay is sensitive enough to measure prolactin concentrations in the sera of most humans studied. The concentration of prolactin in the serum of normal children and adults of either sex was usually below 30 ng/ml, ...
