1. A method comprising:
- a) contacting a sample comprising a plurality of labeled miRNA molecules with an array of probes, each of which probes is;
i. bound to a substrateii. complementary to said labeled miRNA molecules starting at the 3′
terminal nucleotide of said labeled miRNA molecules, to produce a plurality of duplexes between said probes and said labeled miRNA molecules,wherein said plurality of duplexes comprises;
first duplexes in which the 5′
end of said labeled miRNA molecules is hybridized with said probe andsecond duplexes in which the 5′
end of said labeled miRNA molecules is not hybridized with said probe, andwherein the melting temperatures of said duplexes are within 15°
C. of each other; and
b) detecting binding of said miRNA molecules with each of said probes.

Abstract
Aspects of the disclosure are generally directed to probes and probe compositions for detecting or quantifying a target. One aspect provides a method for selectively hybridizing a probe to a polynucleotide by contacting a sample containing a first and second polynucleotide with a probe. The probe includes a number of nucleotides complementary to the first or second polynucleotide in the region of mismatch between the first and second polynucleotides. Another aspect provides arrays including the disclosed probes and methods of using the arrays and the probes.
