    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.
