Electrophoretic Homogeneity of Pregnant Mare Serum Gonadotrophin
A highly purified and potent gonadotrophin in pregnant mare serum has been prepared. The preparation has been shown to be electrophoretically homogeneous in the Tiselius apparatus. The mobilities of the substance have been determined over a wide range of hydrogen ion concentrations. The isoelectric point lies at pH 2.60-2.65 and the value of See PDF for Equation is 4.0 x 10(-5). Some chemical c...
متن کاملEffect of gonadotrophin-releasing hormone aned human chorionic gonadotrophin on the response of the ewe to pregnant mare serum gonadotrophin.
An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...
متن کاملRaised serum human chorionic gonadotrophin concentrations in hyperemesis gravidarum.
Serum human chorionic gonadotrophin (HCG) concentrations were determined by radioimmunoassay with an antiserum specific to HCG beta-subunit in 42 patients with hyperemesis gravidarum and 115 women with normal pregnancies. Mean concentrations (+/- SE of mean) were higher in the women with hyperemesis gravidarum at 7-8 weeks (40.8 +/- 5.2 IU/ml v 22.1 +/- 1.4 IU/ml; P less than 0.001), 9-11 weeks...
متن کاملSerum human chorionic gonadotrophin levels in early pregnancy.
Serum hCG reference intervals for various gestational periods in normal pregnancies were determined using three commercial assays--two standardized against the WHO 2nd IS (Amersham Amerlex-M beta HCG RIA (AMX) and Abbott beta-HCG 15/15 (ABB] and one standardized against the WHO 1 IRP (Hybritech Tandem -E HCG (HYB]. Serial samples from patients with accurately determined gestational periods were...
متن کاملP-76: Stepwise Reduction of Fetal Bovine Serum Levels in Chinese Hamster OvaryCells -Expressing Human Chorionic Gonadotrophin- Culture
Background: The demand for producing recombinant therapeutic proteins by mammalian cell lines, such as Chinese hamster ovary (CHO) cells, continues to grow. Significant achievements in process optimization including development of cell culture strategies for largescale and cost-effective production have been made. Fetal bovine serum (FBS) is an often essential growth supplement and yet most cos...
