A novel RNA Detection Reagent Enables Gene Expression Analysis in Living Cells

14 Apr 2013

Detecting gene expression has traditionally been limited to technologies that examine expression in lysed or fixed cell populations. The ability to detect RNAs in individual, live cells can enable an unequivocal assessment of gene expression changes that occur in direct response to specified perturbations. This application note demonstrates how the new SmartFlare™ detection reagent can be used for detecting specific mRNAs and miRNAs in live, intact cells. The applications of this novel technology are also discussed.

SmartFlare RNA Detection Probes

Merck

SmartFlare Probes work by recognizing specific native RNA sequences within living cells, therefore there are many possible sequences that you could design to recognize your target of interest. Instead of lysed cells, switch to live cells. And while you’re at it, eliminate sample preparation and transfection steps all together. Live cell RNA detection is now possible, in a single incubation step using inert nanoparticle technology to specifically detect native RNA. And when you’re done, the probes exit the cells allowing you to perform downstream analyses with the same, unperturbed cells. Make the smart change!SmartFlare RNA Detection Probes are fueled by the NanoFlare technology developed by renowned chemist Dr. Chad Mirkin.What's Smart? Detect RNA expression in live cells for real time, physiologically relevant data Eliminate laborious, costly sample preparation Easy analysis on the fluorescent detection platform of your choice Nanoparticle based technology that allows cells to be used for downstream assays

Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines.
