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 interfere with hybridization. The biotins can further serve to attach a biotinylated polymer.

18. A method for detecting a target nucleic acid sequence in a sample comprising:
-
rendering the nucleic acid in said sample in single-stranded form; contacting said single-stranded nucleic acid under hybridizing conditions with (i) an oligo- or polynucleotide probe having at least one non-radioactive moiety directly or indirectly attached to each of the 5'"'"' and 3'"'"' end nucleotides thereof, said probe being capable of hybridizing to said target nucleic acid sequence, and (ii) a preformed detectable molecular complex; and detecting any hybridized complexes, thereby detecting the target nucleic acid sequence. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
