Design Notes

This part is codon-optimized for E. coli.

The anionic tag is present to facilitate uptake into our delivery particle MS2 whereas the Histidine tag was added for the purpose of Nickel-Affinity chromatography in obtaining the purified protein.

Source

The Cas13a protein comes from the Gram-negative bacteria Leptotrichia buccalis (Lbu).
