Abstract
A method of determining the presence of a nucleic acid analyte from a sample comprising binding a biotinylated capture oligonucleotide to a solid phase non-covalently coated with streptavidin or an avidin derivative. The capture oligonucleotide is contacted with and selectively hybridized to, under stringent hybridization conditions, a nucleic acid analyte to form a detectable hybridization complex.
Claims11
A low temperature method for determining the presence or absence of a nucleic acid analyte from a sample, said method comprising the steps:
- (a) binding a biotinylated capture oligonucleotide to said solid phase, wherein said solid phase is non-covalently coated with streptavidin or an avidin derivative;
- (b) contacting said capture oligonucleotide with said nucleic acid analyte under stringent hybridization conditions having a temperature of between 25° C. and 40° C. and a chaotrope concentration of at least 1 molar, wherein said capture oligonucleotide selectively hybridizes, under stringent conditions, with said analyte to form a hybridization complex;
- and
- (c) detecting the presence or absence of said hybridization complex as an indication of the presence or absence of said analyte in said sample.
