Biological Activity

BI is a DFHBI derivative for imaging of RNA in cells. BI increases brightness and photostability of Broccoli aptamers in cells. BI enables imaging of single Broccoli-tagged mRNAs in living cells. BI exhibits peak excitation of 470 nm and peak fluorescence emission of 505 nm when bound to Broccoli. BI exhibits higher affinity for Broccoli aptamers and a 10.5-fold increase in cellular fluorescence compared with DFHBI-1T (Cat. No. 5610) (KD values are 51 and 305 nM, respectively).
