The Pre-miR™ hsa-miR-1 miRNA Precursor is intended for use as a positive control in experiments utilizing Pre-miR miRNA Precursors. This precursor was chosen as a positive control because, upon delivery into cells, it effectively down regulates the expression of twinfilin-1, also known as PTK9, at the mRNA level (60-95% reduction. Effective delivery and activity of the Pre-miR hsa-miR-1 miRNA Precursor can be detected by real-time PCR using a TaqMan® Gene Expression Assay to PTK9 (Assay IDs: Hs00702289_s1 [human], Mm01598980_g1 [mouse]).

About Pre-miR miRNA Precursors

Pre-miR™ miRNA Precursor Molecules are small, chemically modified double-stranded RNA molecules designed to mimic endogenous mature miRNAs. These ready-to-use miRNA mimics, which are similar to, but not identical to siRNAs, can be introduced into cells using transfection or electroporation parameters similar to those used for siRNAs. They enable detailed study of miRNA biological effects via gain-of-function experiments (Figure 1). Positive and negative control Pre-miR miRNA Precursors (listed above) or the Pre-miR™ Precursor Starter Kit can be used to optimize transfection of Pre-miR miRNA Precursors.

Pre-miR miRNA Precursor Molecules have been carefully designed and modified to ensure that the correct strand, representing the desired mature miRNA, is taken up into the RNA-induced silencing-like complex responsible for miRNA activity (Figure 2). In contrast to miRNA expression vectors, these synthetic molecules can be used in dose response studies due to their introduction directly into the cell by transfection or electroporation. Thanks to their small size, they are easier to transfect than vectors, and can be delivered using conditions identical to those used for siRNAs.
