Abstract: The present invention is directed to the cloning, sequencing and expression of homologous immunoreactive 28-kDa protein genes, p28-1, -2, -3, -5, -6, -7, -9, from a polymorphic multiple gene family of Ehrlichia canis. Further disclosed is a multigene locus encoding all nine homologous 28-kDa protein genes of Ehrlichia canis. Recombinant Ehrlichia canis 28-kDa proteins react with convalescent phase antiserum from an E. canis-infected dog, and may be useful in the development of vaccines and serodiagnostics that are particularly effective for disease prevention and serodiagnosis.

Abstract: A modified factor VIIa is provided. The modified factor has increased amidolytic activity in the absence of T.F. and a higher affinity for T.F. when compared to the native factor VIIa but does not have substantially altered proteolytic activity when bound to T.F. Nucleic acid molecules that encode the factor, expression vectors that contain the nucleic acid molecules, cells that contain the nucleic acid molecules, and cells transformed with the expression vector are also provided. In a preferred embodiment, the modified factor is a human factor VIIa.

Abstract: The present invention provides an isolated archael and bacterial heme binding protein which reversibly binds oxygen with a low affinity. The heme binding protein may be utilized as a blood substitute. The invention also provides a method for controlled storage of oxygen by contacting a bacterial heme binding protein with oxygen allowing the protein to bind and store oxygen. The also provides methods to sense gaseous ligands using the heme binding protein. In other embodiments, the invention provides chimeric proteins having a heme-binding domain of an isolated heme binding archael bacterial protein and a heterologous signaling domain.
Abstract: The present invention refers to conjugates of erythropoietin with poly(ethylene glycol) comprising an erythropoietin glycoprotein having an N-terminal ?-amino group and having the in vivo biological activity of causing bone marrow cells to increase production of reticulocytes and red blood cells and selected from the group consisting of human erythropoietin and analogs thereof which have the sequence of human erythropoietin modified by the addition of from 1 to 6 glycosylation sites or a rearrangement of at least one glycosylation site; said glycoprotein being covalently linked to one poly(ethylene glycol) group of the formula —CO—(CH2)x—(OCH2CH2)m—OR wherein the —CO of the poly(ethylene glycol) group forms an amide bond with said N-terminal ?-amino group; and wherein R is lower alkyl; x is 2 or 3; and m is from about 450 to about 1350.

Abstract: The present invention is related to a novel composition of matter and methods of using the same. More particularly, the invention describes mutant human factor IX which has an increased resistance to inhibition by heparin. Methods of making and using this composition for the therapeutic intervention of hemophilia are disclosed.
Abstract: Specific amino acid loci of human factor VIII interact with inhibitory antibodies of hemophilia patients who have developed such antibodies after being treated with factor VIII. Modified factor VIII is disclosed in which the amino acid sequence is changed by a substitution at one or more of the specific loci. The modified factor VIII is not inhibited by inhibitory antibodies against the A2 or C2 domain epitopes. The modified factor VIII is useful for hemophiliacs, either to avoid or prevent the action of inhibitory antibodies.
