Integrated DNA Technologies Release: Moving Towards Real-Time Imaging in Single, Living Cells
Published: Jul 10, 2012
By combining Molecular Beacons (MBs) with small interfering RNA (siRNA), Dr Tsourkas’ group has created an all-RNA probe, termed the Ratiometric BiMolecular Beacon (RBMB). Delivered using microporation, the siRNA portion guides localization of the RBMBs to the cell cytoplasm, where they bind to specific mRNAs. These imaging agents make it possible not only to track and visualize individual RNA transcripts, but allow researchers to actually see cell trafficking, measure the velocity of transcript movement, monitor localization within the cytosol, and visualize RNA from transcription through translation.
Dr Tsourkas commented, “We often work closely with IDT to move our research forward and have had a great deal of input from them over the years on probe design. This feedback has been invaluable. We want our technologies to be used by other researchers so it is very important to us that our probes are not only functional, but practical.”
