1. A composition comprising:
- a water soluble polycationic multichromophore conjugated polymer, comprising a backbone of conjugated segments, anda signaling chromophore,wherein the composition is in an aqueous solution, andwherein a greater amount of energy is emitted from the signaling chromophore upon excitation of the conjugated polymer with incident light than from direct excitation of the signaling chromophore with incident light.

Abstract
Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor PNA complementary to the target polynucleotide. The sensor PNA comprises a signaling chromophore to absorb energy from the excited multichromophore and emit light in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.
