      Computational protein engineering · Target to test plan

      Crane Bioworks is a computational partner for protein engineering. We help wet-lab teams decide what to test next, returning ranked candidates, the evidence behind them, and a practical test plan.

      Where Crane adds leverage.

      For wet-lab teams with a clear molecular problem and too many plausible designs to test. Crane narrows the search space into a smaller, defensible candidate set for the next experiment.

      1. More designs than capacity

        A search space too large to test

        The target is clear, but plausible designs outnumber the experiments your lab can run.

        Crane brings: A ranked, annotated candidate set built from cross-checked model outputs.

      2. A decision to defend

        Trade-offs that need a defensible choice

        The models agree on some candidates, diverge on others, and the next experiment needs a rationale.

        Crane brings: Explicit trade-offs and uncertainty translated into a practical test plan.

      3. No expertise in-house

        Focused capacity for the next decision

        Your scientists own the experiments, with no hire to find and no platform to roll out. You need a partner for the heavy computational lifting upfront.

        Crane brings: Model orchestration and scientific judgment delivered as a focused campaign.

      Start with the molecular problem.

      Stability, protein design, enzymes, or complexes: define the next lab decision, then choose the computational route that best reduces the search space.

      Selected campaign

      Stability & Solubility

      When aggregation, solubility, expression, or thermal stability is blocking the next experiment.

      • Aggregation control
      • Expression rescue
      • Developability
      • Thermal stability
      Read the Stability & Solubility solution page

      A handoff your lab can use.

      At the end of a design round, your team receives a well-annotated scientific work product: ranked candidates, explicit uncertainty, and a practical test plan.

      Each candidate stays traceable to model evidence, constraints, uncertainty, and expert review. Your lab can decide what to test now and what the next round should learn.

      Illustrative order

      1. Candidate 01Top priority
      2. Candidate 02
      3. Candidate 03
      4. Candidate 04
      Illustrative prioritization only — your campaign constraints determine the actual ranking and the rationale that accompanies it.
      Design rationale
      Where models agree, where they diverge, which uncertainties remain, and why the final candidates made the cut.
      Validation plan
      What to test first, which assays matter, and how to structure the next round once experimental results come back.
      Next-round plan
      When the lab data arrives we diagnose why designs failed, not only which ones did, so the next round corrects the cause and does not start from zero.

      Start with one target.

      One target, fixed scope, fixed price, typically within 1–3 weeks. From there we engage in long-term partnerships, delivering protein engineering and design services along the lifecycle of a biotech company.

      1. 01

        What you receive

        A decision-ready first round

        Ranked candidates, the rationale, and a validation plan for the target you choose.

      2. 02

        What we need

        Three inputs, no onboarding

        A target sequence, the constraints that matter, and the assay you already run.

        Why not hire

        Expertise without the search

        You get a first answer before a computational hire could be found and onboarded. There is no software to license and no platform for your team to operate.

      A model-agnostic stack, accountable to your team.

      We combine protein language models, structure predictors, generative models, and campaign-specific analyses. Protein engineers cross-check the evidence, quantify uncertainty, and turn it into priorities your lab can test.

      Ask how a campaign works, talk through a public result, or clarify fit before a call. When the conversation moves from explanation to scope, the Crane team takes over.

      Scientific review

      Trusted advisors

      Senior scientific advisors review approach and results behind the scenes, adding a layer of judgment and accountability to every design campaign.

      Answers before you share a sequence.

      Practical answers before we discuss target context.

      Ranked, well-annotated candidate designs, the rationale behind them, explicit uncertainty, a validation plan, and a clear route into the next round when lab data comes back.

      Bring the next molecular decision.

      In 30 minutes, we’ll look at the target sequence, known constraints, and experiments your lab can run, then tell you directly whether a focused computational campaign can shrink the search space.
