Part:BBa_K4438100
FASTmiR-222-D1
FASTmiR stands for Fluorescence Aptamer Sensor For Tracking miRNAs. It is an RNA-based sensor for in-vitro quantification of miRNAs. FASTmiR-222-D1, after transcription, binds to miR-222, the transcription product of BBa_K4438150. The binding of these to RNAs will lead to the revelation of a binding site for DFHBI, a fluorophore, where it gets trapped and shows fluorescence.
Usage and Biology
This part can be used for the detection of miR-222, which proves to be a biomarker for many diseases. The OFF(A) and ON(B) structure for the sensor was generated as given:
