FASTmiR-222-D1_p

FASTmiR stands for Fluorescence Aptamer Sensor For Tracking miRNAs. It is an RNA-based sensor for in-vitro quantification of miRNAs. This part is the expression cassette for BBa_K4438100 with BBa_J64997 upstream. FASTmiR-222-D1_p, after transcription, binds to miR-222, the transcription product of No part name specified with partinfo tag.. 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 promoter sequence, in the beginning, enhances its usage in both in-vivo and in-vitro conditions. The ON and OFF structure for the sensor was generated as given:
