Background

In order to determine the PLP sequence that yields the best reaction kinetics, we designed padlocks with the crRNA recognition site (responsible for binding with the crRNA in RNP and activating Cas12a cleavages) at different locations.

Design

In Padlock-miR-223-4（Padlock-4）, the Cas12a detection module (square brackets) is placed in the middle.
Sequence:
TCAAATACACG-AGATACCCT-[CGTCGCCGTCCAGCTCGACC]-AACCATCGAT-AACTCAGCTTG

Results

The following figure shows the final values for padlocks 1-4 (padlock 1 is BBa_K4664002, aka. Padlock-223).
