    摘要: The present invention discloses a process for the preparation of rhPTH (1-34) also known as teriparatide by construction of a novel nucleotide, as an NcoI.IXhoI fragment as set forth in SEQ. ID. No.:1 encoding a chimeric fusion protein as set forth in SEQ.ID. No.:2 comprising of a fusion partner consisting of 41 amino acids belonging to Escherichia coli β-galactosidase (LacZ) gene, an endopeptidase cleavage site, rhPTH (1-34) gene fragment, cloning the said nucleotide in an expression vector under the control of T7 promoter, transforming Escherichia coli with the said vector and expressing the chimeric fusion protein in fed batch fermentation. The present invention further discloses a low feed rate lactose induction for optimized expression of rhPTH (1-34) in Escherichia coli. The present invention also discloses an unique, novel two step orthogonal purification process for rhPTH (1-34) comprising of cation exchange chromatography optionally followed by preparative chromatography selected from HIC or RP-HPLC to yield a target protein of ≧99% purity. The present invention discloses a simple, cost-effective, environmentally benign method of producing high purity rhPTH (1-34).

    摘要: This present invention is directed to polypeptide and polynucleotide molecules that encode a four-helical bundle cytokine. The cytokine has been designated zsig81, and has restricted expression in primarily heart, lung and liver. zsig81 has been shown to stimulate proliferation of hematopoietic cells and will be useful expansion of these cells, as well as conditions associated with hematopoietic cells. The invention is directed to antibodies and methods of making zsig81 polypeptides, as well.

    摘要: Chicken II and salmon GnRH analog decapeptides resistant to degradation by peptidase incorporating D-arginine, D-leucine, D-tBu-Serine, D-Trp or other active D amino acids at position 6 and ethylamide, aza-Gly-amide or other Gly amide at position 10. The analogs demonstrate preferential binding to male and female reproductive system GnRH receptors. Biopotency is greater within the reproductive system than at the pituitary. These non-mammalian GnRH analogs may be used in pharmaceutical preparations, and specifically in various treatment methods as a contraceptive or post-coital contraceptive agent. The non-mammalian GnRH analogs are also provided in pharmaceutical preparations that may be used clinically for maintaining pregnancy when used in very low doses and administered in pulsatile fashion, as well as in preparations for the treatment of male and female reproductive system disorders. The aza-Gly (10) amide non-mammalian analogs are yet other embodiments of the non-mammalian GnRH analogs provided as a part of the invention.
