    Abstract: The invention provides a method for detecting a target nucleotide sequence by tagging the nucleotide sequence with a nucleotide tag, providing a probe oligonucleotide with a melting temperature Tm1, comprising a regulatory sequence and a nucleotide tag recognition sequence; incorporating the probe oligonucleotide into the tagged polynucleotide in a polynucleotide amplification reaction, providing a regulatory oligonucleotide with a melting temperature Tm2, comprising a sequence segment that is at least partially complementary to the regulatory sequence, amplifying the tagged target nucleic acid sequence in a PCR amplification reaction using the probe oligonucleotide as a primer, and detecting the amplification product; wherein Tm1 and Tm2 are higher than the annealing temperature associated with the polynucleotide amplification reaction.

    Abstract: Methods and reagents for detection and analysis of nucleic acids are provided. Certain methods involves an encoding amplification in which a target sequence is associated with probe-binding sequences and optionally with indexing sequences, (2) an optional distribution step in which the product of the encoding amplification is split into multiple aliquots, and (3) a decoding and detection step in which the presence, absence, quantity, or relative amount of the target sequence in the aliquots is determined. The detection step makes use of a multifunctional “self-digesting” molecular probe comprising a primer polynucleotide and a probe oligonucleotide, linked in a 5′-5′ orientation.
