Abstract

Abstract An oligo- or polynucleotide having at least one biotin directly or indirectly attached to each of the 5' and 3' end nucleotides thereof and a nucleic acid hybridization assay system for use therewith. The biotins are optionally attached through linkage groups that do not interfer with hybridization. The biotins can further serve to attach a biotinylated polymer.
