What is the Cell-Free Expression skill?

It is a specialized Claude Code skill designed to provide expert guidance and best practices for cell-free protein synthesis (CFPS) optimization, helping researchers improve protein yield and quality.

How can it help with protein folding and solubility?

The skill offers detailed strategies for disulfide bond formation, the use of fusion tags like MBP or SUMO, and specific chaperone supplementation protocols to prevent aggregation.

Which expression systems does this skill cover?

It provides selection criteria and data for various systems including E. coli (extract and PURE), Wheat germ, Rabbit reticulocyte, Insect (Sf21), and HeLa/CHO systems.

When should I use this skill?

Use it when planning CFPS experiments, troubleshooting low protein yields, or designing mRNA templates for expressing difficult, toxic, or membrane-bound proteins.

Does it provide codon optimization advice?

Yes, it includes specific rules for E. coli CFPS, identifying rare codons to avoid and explaining how to design the first 30 codons to maximize translation initiation.
