​
What you get

  • Expression call: Expressed / low / not detected
  • Relative yield: Comparable signal per variant for quick triage
  • QC summary: Flags for insolubility or tag issues

​
How it works

We run your sequences through our standardized cell‑free expression workflow and detect expression via tag‑based readouts. Expression is confirmed and quantified with a split‑GFP reporter, and results land in your dashboard and API with clear calls and QC.

​
When to use

  • Before binding or activity campaigns to avoid running non‑expressers
  • During library exploration to focus on productive designs

FAQs

We support roughly 50 to 700 amino acids, covering antibody-derived formats, engineered scaffolds, and de novo proteins. Longer constructs cost more to synthesize; very short peptides are usually limited by yield rather than folding. See Supported Protein Formats.
Our QA flags anomalies continuously during data generation, and we re-run a sample when a call is not clear-cut rather than reporting an ambiguous result.
Yes. Our default runs express only enough material for the assay. When you want protein in hand, see Expression Scale-Up.
