  • Patent number: 11518819
    Abstract: The present invention provides a bi-functional fusion protein, (AT)a-Fc-(VT)b, simultaneously targeting vascular endothelial growth factor (VEGF) and angiopoietins (ANGs), wherein AT is an ANG binding motif; and VT is a VEGF binding motif, Fragment crystallizable region (Fc) is an N-terminal of Immunoglobulin G (IgG); each of a and b is an integer from 1 to 10. The bi-functional fusion proteins contain two or more domains of human proteins and are of all human sequences, and thus are expected to be non-immunogenic, and potentially can be used therapeutically in human targeting angiogenesis-associated diseases.

  • Publication number: 20050100911
    Abstract: The invention provides several methods for reducing the complexity of a population of nucleic acids prior to performing an analysis of the nucleic acids on a nucleic acid probe array. The methods result in a subset of the initial population enriched for a desired property, or lacking nucleic acids having an undesired properly. The resulting nucleic acids in the subset are then applied to the array for various types of analysis. The methods are particularly useful for analyzing populations having a high decree of complexity, for example, chromosomal-derived DNA, or whole genomic DNA, or mRNA population. In addition, such methods allow for analysis of pooled samples.

  • Publication number: 20030215453
    Abstract: Certain cells, including types of cancer cells such as B-cell lymphoma, T-cell lymphoma, T-cell leukemia, and non-Hodgkin's lymphoma, are capable of expressing VpreB1 RNA. Immunotargeting using VpreB1 polypeptides, nucleic acids encoding for VpreB1 polypeptides and anti-VpreB1 antibodies provides a method of killing or inhibiting that growth of cancer cells that express the VpreB1 protein. Methods of immunotherapy and diagnosis of disorders associated with VpreB1 protein-expressing cells, such as B-cell lymphoma, T-cell lymphoma, T-cell leukemia, and non-Hodgkin's lymphoma, are described.
