Patent ID: 7901883

Claim:
A beadset for detecting a strain of HPV and/or for differentiating between two or more strains of HPV, wherein the beadset comprises a plurality of subsets of beads wherein: (a) the beads of each subset are homogenous with respect to size; (b) the beads within each subset are coupled to a nucleic acid capture probe which is capable of binding to a HPV strain-specific region of an HPV genome; (c) the capture probe on each bead is labeled with the same label with each subset of beads having a different fluorescent intensity to create a heterogeneous mixture of beads based on fluorescent intensity wherein the nucleic acid capture probe is selected from the group; and (d) at least two subsets of beads are mixed together to produce a beadset, wherein the subset identity and therefore the strain of HPV is identifiable by flow cytometry based on size, fluorescent intensity and sequence discrimination.
