PACCMIT/PACCMIT-CDS: identifying microRNA targets in 3' UTRs and coding sequences.

abstract：:Quantitative real-time PCR has revolutionized many aspects of genetic research, biomedical diagnostics and pathogen detection. Nevertheless, the full potential of this technology has yet to be realized, primarily due to the limitations of the threshold-based methodologies that are currently used for quantitative analy...
