Abstract: Provided herein are compositions, systems, kits, and methods for expressing a peptide of interest, such as Apolipoprotein H (ApoH), also known as ?2-glycoprotein I (?2GPI), at increased levels using a non-ApoH signal peptide (e.g., a signal peptide that permits increased protein export from cells). Also provided herein are compositions, systems, kits, and methods for employing such recombinant ApoH with a non-ApoH signal peptide to detect subject Apolipoprotein H antibodies in a sample from a subject (e.g., to diagnose antiphospholipid syndrome in a subject).

Abstract: The present invention relates to a device for extracorporeal removal of harmful agents from blood or blood com-Components, comprising full length heparin immobilized on a solid substrate by covalent end point attachment. The present invention also relates to a method for extracorporeal removal of a harmful agent from mammalian blood or blood components. The present invention further relates to a process for covalent end point attachment of full length heparin to a solid substrate.

Abstract: The present invention is directed to novel methods for inhibiting angiogenesis and treating tumors and cancer by targeting tropomyosin (Tpm) expressed on the surface of endothelial cells and/or tumor cells, to Tpm polypeptides and peptides, as well as variants and derivatives thereof that bind inhibitors of angiogenesis, and to anti-Tpm antibodies that block or stimulate angiogenesis. Cyclic peptides that bind to the D5 subunit of HKa and inhibit angiogenesis are also included. Method for screening test compounds as candidate antiangiogenic molecule that binds to Tpm are disclosed, as are affinity ligands comprising the proteins, peptides, variants and derivatives of the invention.
