Mirna control

Manufactured by GenePharma
Sourced in China

The MiRNA controls are a set of synthetic RNA molecules designed to serve as positive and negative controls for microRNA (miRNA) analysis. These controls are used to validate the performance and accuracy of miRNA detection and quantification methods, such as real-time PCR, Northern blotting, or microarray analysis. The MiRNA controls provide a reliable and consistent standard for assessing the sensitivity, specificity, and reproducibility of miRNA-based experiments.

The HOXA11-AS overexpression plasmid, i.e. pcDNA3.1-HOXA11-AS, was acquired from Genearray Biotechnology (Shanghai, China), which was transfected to SCC-25 cells, followed by G418 selection. Briefly, the SCC-25 cells, which were seeded in 24-well plates at the density of 1 × 105 cells/cm2, were grown in complete medium containing 250 mg/mL G418 (Sigma-Aldrich, USA). After 48 h of transfection, cells were cultured for 4 weeks at 1:10 (v/v) in medium with 600 μg/mL G418. The resulting clones, termed as HOXA11-AS cells, were maintained in medium with 300 μg/mL G418. cloning qRT-qPCR was used to confirm HOXA11-AS overexpression in cells.

Cervical cancer cells (2 × 105 cells) were transfected with 1 μg of a plasmid expressing miR-486-5p inhibitor sponge, miR-486-5p mimic, or control miRNA (Genepharma, Shanghai, China). Transfection into cells was carried out according to the manufacturer’s instructions using Lipofectamine3000 for 48 h (Invitrogen–Life Technologies). Stable expression of each miRNA was established in the cells after 15 days of incubation in complete DMEM with blasticidin (12 μg/mL). We verified miRNA expression in the clones using real-time PCR and integrate all the successful clones for the subsequent experiments.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
