  • Patent number: 8512953
    Abstract: The invention provides methods for detecting target nucleic acid sequences with diagnostic probes including first and second probe regions that are substantially complementary to first and second target regions respectively on a target nucleic acid strand wherein the first probe region is located 5? to the second probe region. The first probe region is substantially complementary to the first target region, on the target nucleic acid strand, which also includes a second target region, wherein when said first target region is contiguous with the second target region on the target nucleic acid strand, then the first and second probe regions on the diagnostic probe are separated by a spacer region of nucleic acid.

  • Patent number: 6514714
    Abstract: The present invention provides an improved method for detection of panel reactive antibodies in serum of a subject against HLA class I antigens, which comprises the steps of adding serum from a subject to an array of microbeads, each microbead presenting HLA antigens from a cell population presenting the same HLA antigens; incubating the serum and microbeads for sufficient time for anti-HLA antibodies in the serum to bind to the HLA antigens presented on the microbeads; removing the serum components which do not specifically bind with the HLA antigens presented on the microbeads; incubating the microbeads with a labeled ligand capable of specifically binding with anti-HLA antibodies bound to said HLA antigens; removing the labeled ligand which is not bound to said HLA antigens; and detecting the presence of labeled ligand bound to said HLA antigens by flow cytometry.

  • Patent number: 6150122
    Abstract: The present invention provides a kit for the improved method for detection of panel-reactive antibodies in serum of a subject against HLA Class I antigens, which comprises an array of microbeads, each microbead presenting HLA antigens from a cell population presenting the same HLA antigens. In the method, serum from a subject is added to said array of microbeads then the mixture is incubated for a sufficient time for anti-HLA antibodies in the serum to bind to the HLA antigens presented on the microbeads. After removing serum components which do not specifically bind with the HLA antigens presented on said microbeads, the microbeads are incubated with a labeled ligand capable of specifically binding with anti-HLA antibodies bound to said HLA antigens. The labeled ligand which is not bound to said HLA antigens are removed and the presence of labeled ligand bound to said HLA antigens are detected by flow cytometry.
