  • Publication number: 20080207487
    Abstract: The present invention provides a manufacturing method for polypeptides that are produced in insect cells using a baculoviral expression system. In one example, the insect cell culture is supplemented with a lipid mixture immediately prior to infection (e.g., one hour prior to infection). The polypeptides are isolated from the insect cell culture using a method that employs anion exchange or mixed-mode chromatography early in the purification process. This process step is useful to remove insect-cell derived endoglycanases and proteases and thus reduces the loss of desired polypeptide due to enzymatic degradation. In another example, mixed-mode chromatography is combined with dye-ligand affinity chromatography in a continuous-flow manner to allow for rapid processing of the insect-cell culture liquid and capture of the polypeptide.

  • Patent number: 7250493
    Abstract: Fc fusion proteins of human EPO with increased biological activities relative to rHuEPO on a molar basis are disclosed. The HuEPO-L-vFc fusion protein comprises HuEPO, a flexible peptide linker of about 20 or fewer amino acids, and a human IgG Fc variant. The Fc variant is of a non-lytic nature and shows minimal undesirable Fc-mediated side effects. A method is also disclosed to make or produce such fusion proteins at high expression levels. Such HuEPO-L-vFc fusion proteins exhibit extended serum half-life and increased biological activities, leading to improved pharmacokinetics and pharmacodynamics, thus fewer injections will be needed within a period of time.

  • Patent number: 7241577
    Abstract: Methods and kits are provided for assessing the ovarian reserve and predicting the ovarian response to fertility treatments in a female subject. The serum levels of MIS are shown to be positively correlated with the production and retrieval of mature oocytes and serve as prognostic indicators for the female response to fertility treatment. The MIS levels can be monitored prior to and during fertility treatment and are useful to adjust the timing and dosage of treatments in order to produce optimal outcome in individual patients, to avoid ovarian hyperstimulation, or to indicate cancellation of an unsuccessful treatment. MIS can also be administered to women to stimulate follicle development and to prevent depletion of ovarian reserve.

  • Patent number: 7211253
    Abstract: The invention relates to novel modified erythropoietin (EPO) forms such as fusion proteins comprising a Fc portion of an Ig molecule and a target molecule having the biological activity of EPO. By selective altering of the amino acid sequences of the erythropoietin moiety as well as of the immunoglobulin moiety and the glycosylation pattern of erythropoietin fusion proteins with enhanced biological activity can be obtained. The invention relates also to novel nun-fused EPO molecules which have a pattern of cysteines or disulfide bonding which is distinct from human or animal EPO.

  • Patent number: 7196060
    Abstract: The present invention relates generally to the fields of immunology and molecular biology, and particularly to a method for treating hematopoietic disorders. The invention provides a method to treat a deficiency of one or more types of blood cells in a mammal, which includes administering an effective amount of TISF or of a compound that stimulates CD4+ cells like TISF does. In one embodiment, TISF that originates from a mammalian species is administered to a mammalian subject diagnosed as having a deficiency in one or more types of blood cells.
