3WJ-Bro

3WJ-Bro is used as a protein- independent reporter system based on a fluorescent RNA aptamer. 3WJ-Bro is applied as a gene marker in creating a system for reporting the presence and expression of target gene, which is relE toxin gene at the transcriptional level in the project of CAFA_China (2022). The 3WJ-Bro can be used to ligate fluorescent aptamers to examine the relE RNA at transcriptional level in Escherichia coli cells, obviating the need for accumulation of foreign proteins.

  • After bacterial culture and UV induction, we measured the OD600 and fluorescence values under 485/510nm. Then, the fluorescence per OD was calculated.
  • According to the results, the 3WJ-Bro can be used to ligate fluorescent aptamers to examine the relE RNA synthesis at transcriptional level.
  • With the lengthening of culture time, the RNA synthesis of relE increased gradually as shown bellow:
3WJ-Bro was ligated with fluorescent aptamers in order to examine the level of relE RNA synthesis (485/510nm).
