The signature sequence amplification method (SSAM) described herein is an approach for amplifying noncoding
RNA (ncRNA), microRNA (miRNA), and small polynucleotide sequences. A key point of the SSAM technology is
the generation of signature sequences. The signature sequences include target sequences (miRNA, ncRNA, and/or any
small polynucleotide sequence) flanked by two DNA fragments. Target sequences can be amplified through DNA synthesis,
RNA synthesis, or the combination of DNA and RNA synthesis. The amplification of signature sequences provides an
efficient and reproducible mechanism to determine the presence or absence of the target miRNAs/ncRNAs, to analyze the
quantities of the miRNAs in biological samples, and for miRNA/ncRNA profiling.
