Design Notes

Amino acid sequence reverse transcribed and codon optimized for expression in E. coli B (the parent strain of SHuffle).

His tag and TEV cleavage sites were included downstream of the start codon but upstream of the antibody coding sequence. The His tag ensured the entire polypeptide could be purified out of a total protein solution using immobilized metal ion affinity chromatography (IMAC), and the TEV cleavage site ensured that TEV could be used to cleave off the His tag once it was no longer needed.
