Abstract: The invention is directed to methods of screening for HLA antibodies comprising detecting antibodies specific for native HLA antigens and denatured HLA antigens. The invention also provides for methods of removing antibodies specific for denatured HLA antigens or antibodies specific for native HLA antigens from a serum sample. In addition, the invention also provides for method of predicting whether a transplant recipient has an increased risk for rejecting the transplanted organ.

Abstract: The present invention relates to methods for screening for binding interactions using multiple sets of microparticles, wherein said set has the same identifiable characteristic and wherein one of more sets comprise subsets of microparticles and said subset presents at least one unique probe that acts as a binding partner for a target molecule in a biological sample. In particular, the invention provides for methods of detecting tissue-typing antigens in donor tissue or recipient tissue using these multiple sets of microparticles.

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.

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.

Abstract: The invention provides methods for detecting target nucleic acid sequences with diagnostic primers including priming regions and probe regions which are complementary to target and reference regions respectively on a sample nucleic acid strand wherein the probe region is located 5′ to the priming region which is complementary to a reference nucleic acid sequence which is 3′ to the target nucleic acid sequence on the sample nucleic acid strand wherein when said reference nucleic acid sequence is contiguous with said target nucleic acid sequence on the sample nucleic acid strand then the priming region and probe region on the diagnostic probe are separated by a spacer region of nucleic acid.
