Abstract
The present invention provides a method of detecting and a method of quantifying oligonucleotides with more excellent specificity and quantitativity as compared to conventional signal amplification (PALSAR) measurement methods. In the present invention, the problem is solved by hybridizing a target oligonucleotide to be measured with a complementary nucleic acid probe (3′-complementary sequence of target sequence-5′), or hybridizing the target oligonucleotide to be measured having given bases such as poly(A) added thereto with a complementary nucleic acid probe (3′-complementary sequence of target oligonucleotide+complementary sequence of given bases-5′), decomposing and removing an incomplete hybridization product by using a single-strand-specific nuclease such as Si nuclease, and measuring the nucleic acid probe contained in a remaining complete hybridization product by a PALSAR method.
