Cas Proteins

The characterization of the production of proteins was mesure using the Biuret method to cuantify the total proteins under the induction with IPTG. Using controls of BL21 0 mM IPTG and BL21 transformed with Cas 1 and Cas 2 0 mM IPTG. We used different concetration of IPTG of 0 mM, 0.1 mM, 0.5 mM and 1 mM, and inducted for 6 hours taking samples every 30 min for 1 mM IPTG and every hour for the rest of the samples. Determining that the concentration of 0.1 mM has the highest concentration of total proteins.

Total RNA extraction was performed with IPTG induced E coli transformed with the msDNA construct.

Cotransformation demonstration
In order to demonstrate the functionality of our proyect we made a electrophoresis gel to see the amplification of the two Crispr Arrays in E. Coli Bl21 (DE3). This strain contains 2 Crispr Arrays, one pf 2016 bp long and other one of 996 bp long. The insertion contained 61 bp of difference between the expanded array and the not expanded (33 bp of the optimized oligo and 29 bp for the repeat). We decided to carry out both PCR amplification, due to the equal posibilities of insertion in the different Arrays. In our results we were able to see the correct amplification of the Array 1 (277 bp of length) 216 bp long + 61 bp of their expansion.

Conclusion
In conclusion, the system is capable of inserting sequences inside of CRISPR arrays found in the genome of the bacteria. The SCRIBE system was able to produce a sequence induced by IPTG.
