Merck Millipore SmartFlare detection reagent for live cell RNA

Friday, 31 May, 2013 | Supplied by: Merck Pty Ltd

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. Determining which genes are up- or down-regulated in these perturbed cells provides insight into the relationships between gene expression networks and cell functions.

The SmartFlare detection reagent is a novel probe capable of detecting specific mRNAs and miRNAs in live, intact cells. The technology allows for carrier-free cellular endocytosis of the reagent, followed by detection and relative quantitative analysis of RNA levels.

Because the reagent leaves the cell after the detection event, the same sample can be used for any downstream analysis, meaning the user can assess multiple biomarkers or downstream functionalities in the same cells. Additionally, the reagent requires no upfront sample preparation, has no toxic effects on cellular fate and no known non-specific, off-target effects.

Compared to currently used methods for interrogating RNA that involve examination of non-native, amplified RNA targets, the product has the potential to provide results that show greater correlation to in vivo observations.
