MicroRNAs (miRNAs) are small, non-coding single stranded RNA molecules found in eukaryotic organisms. They are highly conserved and usually 21-23 nucleotides in length. miRNAs are involved in almost all cellular functions and regulate gene expression by binding to the 3' untranslated regions (3' UTRs) of targeted mRNAs. Irregularities in miRNA-regulated gene expression have been found to be associated with cancers, cardiovascular disorders and a variety of other diseases.
GeneCopoeia offers miExpress precursor miRNA expression clones in lentiviral and non-viral vectors with eGFP reporter gene. Hairpin precursor miRNA of approximately 150 nucleotides is cloned into lentiviral or non-viral vectors for delivery in virtually all cell types.
