sgRNA
Profile
Name: sgRNA
Base Pairs: 112bp
Origin: Lactobacillus casei, genome
Properties: A piece of RNA
Usage and Biology
BBa_K4099000 is a piece of RNAs that function as guides for RNA- or DNA-targeting enzymes, which they form complexes with.
The sgRNA and HR are inserted in the pLCNICK vector. (Figure 3).
Proof of function
We electrotransformed the plasmid pIB165 as the foreign DNA to test the transformation efficiency of our modified L. casei, it took several days to culture and finally saw the comparison results. As showing above, we can see that the modified L. casei (KO) has higher transformation efficiency with remarkably more colonies than the wild (Wild).

Graph 3. Comparison between the wild L. casei and modified L. casei in transformation
In addition, we measured OD600 of these strain groups which were pre-spread plates with different volumes of bacteria solutions so as to quantify the transformation results as showing above (Fig. 3). In conclusion, it indicates that our modified L. casei has much higher efficiency of the foreign plasmid transformation than the wild and the modified L. casei has great potential to be used as the recombinant carrier in various areas.
