Human pituitary and placental hormones control human insulin-like growth factor II secretion in human granulosa cells.
Human granulosa cells cultured with calf serum actively proliferated for 18-20 generation and secreted progesterone into the medium; progesterone levels appeared to decline with increase in generation number. Cells cultured under serum-free conditions secreted significant amounts of progesterone and insulin-like growth factor II (IGF-II). The progesterone secretion was enhanced by the addition ...
متن کاملEvaluation of dual-label simultaneous assays for lutropin and follitropin in serum.
We evaluated the analytical performance and clinical utility of three dual-label simultaneous assays for lutropin and follitropin by comparison with widely used individual assays for these analytes (Diagnostic Products Corp.; DPC). Of the three assays evaluated, "Cotropin" (Clinetics Corp.) and "Combostat" (Micromedics Systems, Inc.) compared favorably with the DPC assay with respect to recover...
متن کاملAssessment of the biopotency of follitropin alfa and lutropin alfa combined in one injection: a comparative trial in Sprague-Dawley rats
BACKGROUND The current study was designed to determine if follitropin alfa (recombinant human follicle-stimulating hormone; r-hFSH) and lutropin alfa (recombinant human luteinizing hormone; r-hLH) biopotencies were unchanged by reconstituting in sterile water for injection and mixing prior to injection. METHODS The biopotencies of r-hFSH and r-hLH were determined following injection of female...
متن کاملPregnant mare serum gonadotropin. An in vitro biological characterization of the lutropin-follitropin dual activity.
The interaction of highly purified pregnant mare serum gonadotropin (PMSG or eCG) has been studied in rat and equine testis homogenates. In the rat studies, unlabeled PMSG was shown to possess both high levels of intrinsic follitropin-like and lutropin-like activity when the inhibition of radioiodinated follitropin and lutropin binding by unlabeled PMSG was studied. Radioiodinated PMSG exhibite...
متن کاملDouble-label time-resolved immunofluorometry of lutropin and follitropin in serum.
We describe a procedure for the simultaneous immunofluorometric assay of lutropin and follitropin in human serum, based on the use of monoclonal antibodies and of the fluorescent lanthanides Eu3+ and Tb3+. The alpha-chain-specific antibody was used as a common capture antibody on the surfaces of microtitration strips. The anti-beta-follitropin antibody was labeled with Tb3+, the anti-beta-lutro...
