The present invention provides conjugates between follicle stimulating hormone and PEG moieties. The conjugates are linked via an intact glycosyl linking group that is interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from both glycosylated and unglycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto either an amino acid or glycosyl residue on the peptide. Also provided are pharmaceutical formulations including the conjugates. Methods for preparing the conjugates are also within the scope of the invention.

A method for synchronizing ovulation in sows and gilts by a single injection of hormones is disclosed. A hormone, gonadotropin releasing hormone (GnRH), luteinizing hormone (LH), follicle stimulating hormone (FSH), human chorionic gonadotropin (hCG), analogues, derivatives, agonists or combinations thereof is administered to an open sow post weaning at a specific time to stimulate ovulation of mature responsive follicles. The sow is then bred, without heat detection, at a specific subsequent timed interval after injection with hormone, with one or two artificial or natural breedings. In gilts, the hormone is injected at a timed interval from onset of estrus or at a specific timed interval following Prostaglandin F2a for those gilts which have been held in a state of pseudopregnancy.

The invention discloses a superovulation method for goats. The superovulation method comprises the following steps of: selecting female goats which can be applied to superovulation; teasing in the morning and at the night every day; counting from day zero when oestrum is observed for the first time; injecting follicle stimulating hormone once in the morning and at the night on the fourth day, the fifth day, the sixth day and the seventh day respectively; injecting cloprostenol during the injection of the follicle stimulating hormone in the morning and at the night on the seventh day; injecting luteotropin on the eighth day; performing semen deposition through a laparoscope; and recycling a pronuclear embryo on the tenth day or collecting a mulberry body on the sixteenth day. A progesterone needing process in the conventional superovulation method for goats is eliminated, production time is shortened, and production cost is reduced; simultaneously, with the method, superovulation efficiency which is the same as that of the conventional superovulation method can be achieved and an experimental result of each batch indicates that each goat can obtain 8 to 30 embryos on average.

Methods are provided for the establishment and maintenance in long term culture of hormone secreting cells. Cells are derived from tumorous or non-tumorous animal or human tissues, including ovary, endometrium, trophoblast, pituitary, thyroid, and pancreas. The cells secrete into the culture medium hormones such as estrogens, progestins, follicle-stimulating hormone, luteinizing hormone, human chorionic gonadotrophin, thyroxin, glucagon, and insulin, depending on the tissue of origin of individual cell cultures. Contact with an appropriate secretogogue causes the cells to respond with increased hormone secretion. For instance, ovarian follicular cells respond to follicle-stimulating hormone with increased estrogen and progesterone secretion. Pancreatic cells respond to elevated glucose with increased insulin secretion. The cells proliferate in in vitro for up to one year or longer, during which time they retain their hormone-secretion profile. The cells may be frozen for storage, and retain their hormone-secretion profile after thawing. The cell cultures are useful for the production of human hormones, for the bio-assay of drugs such as therapeutic gonadotrophin, for the testing of drug efficacy and design, and for toxicity testing of drugs and chemicals. The cells may also be implanted in an individual to replace deficient hormone secretion. For instance, insulin secreting pancreatic cells may be implanted in a diabetic individual as an adjunct or replacement therapy for exogenously administered insulin.
