    摘要： Flow cytometric methodology is provided for simultaneous determination of (1) ABO and Rh(D) typing of human red cells, (2) natural isoantibodies in plasma, and (3) screening for alloantibodies in plasma. The method includes (a) the use of a unique combination of fluorescent labelled antibodies to A, B and Rh(D) antigens to carry out (1); (b) different sized beads coated with blood group substances A & B to carry out (2); and (c) the differential fluorescent labelling of screening reagent red blood cells for flow cytometric analyses to carry out (3). The routine ABO and Rh(D) typing and antibody screening of human blood for both isoantibodies and alloantibodies can be determined in three individual reactions compared to 7 to 10 tests currently performed in blood banks.

    摘要： Disclosed herein are two methods for rapid multiplex analysis to determine the presence and identity of target DNA sequences within a DNA sample. Both methods use reporting DNA sequences, e.g., modified conventional Taqman® probes, to combine multiplex PCR amplification with microsphere-based hybridization using flow cytometry means of detection. Real-time PCR detection can also be incorporated. The first method uses a cyanine dye, such as, Cy3™, as the reporter linked to the 5′ end of a reporting DNA sequence. The second method positions a reporter dye, e.g., FAM, on the 3′ end of the reporting DNA sequence and a quencher dye, e.g., TAMRA, on the 5′ end.
