stem-loop test

Introduction

This compoiste part is a stem-loop-deleted version of BBa_K4765120, which includes stayGold and mScarlet. Its red-green fluorescence intensity ratio can be compared with BBa_K4765120 to assess the stem-loop's ability to prevent mRNA degradation.

Usage and Biology

We use this composite part to test the following stem-loops'^[1] ability to prevent mRNA degradation.

Characterization

Sequencing map

Figure 1. Sequencing result of nsl (no stem-loop before Twister ribozyme cleavage site). Sanger sequencing verified that we have removed the stem-loop before ribozyme sequence, from BBa_K4765120. We also construct plasmids with stem-loop new2, new6, new10, bad2, bad6, bad10, all of which were designed by our Software RAP, and fully characterized using functional assays.
