General description
RNA G-quadruplexes are formed by self-assembly of guanine-rich RNA stacks into stacked G-quartets. This can occur in protein-coding (mRNA) as well as non-coding (ncRNA) transcripts. There is growing evidence that RNA G-quadruplexes are involved in different biological functions: telomere elongation, DNA recombination, transcription, RNA post-transcriptional mechanisms (pre-mRNA processing, mRNA turnover, targeting and translation), and are associated with sevral human diseases.
BioTracker<TMSYMBOL></TMSYMBOL> QUMA-1 RNA G-quadruplex Live Cell Dye (QUMA-1) is a red-emitting fluorescent probe that can be used to study dynamics (folding and unfolding) and movements of RNA G-quadruplexes. QUMA-1 is a reversible dye that emits upon binding to G-quadruplexes and turns off upon unfolding. QUMA-1 is highly specific for RNA G-quadruplexes and does not bind to DNA, double-stranded RNA, single-stranded RNA or other RNA structures. QUMA-1 could also potentially be used to study RNA-protein interactions.

Absorbance: 555 nm
Emission: 660 nm

Because of the absence of methods for tracking RNA G-quadruplex dynamics, especially the folding and unfolding of this attractive structure in live cells, understanding of the biological roles of RNA G-quadruplexes is so far limited. Herein, we report a new
