Count (designs with an observed binding signal (SPR against full-length apo SpCas9), out of designs tested) of BindCraft default settings on BindCraft binder design target SpCas9

All six tested binders bound the full-length apo SpCas9 enzyme Count (designs with an observed binding signal (SPR against full-length apo SpCas9), out of designs tested)

Evidence concern: excluded from comparisons

Supplementary Data 1 has one row per tested design with a Binding column holding 1, 0 or an empty cell. Treating the non-empty cells as the tested set reproduces the prose counts for BBF-14 (11 tested, 6 binding), Bet v1 (7, 2), CD45 (16, 4), Der f7 (10, 4), Der f21 (7, 4), IFNAR2 (9, 3), PD-1 (53, 13), SpCas9 (6, 6) and CLDN1 (7, 6), but not for PD-L1 (13 non-empty rows with 11 binding against 9 tested with 7 binding in the prose), CrSAS-6 (10 non-empty rows against 9 tested) or CbAgo (2 non-empty rows against 12 tested). The row filter is therefore ambiguous and no value is computed from these rows.One-shot design of functional protein binders with BindCraft (Pacesa et al., Nature 2025) · Supplementary Data 1 (41586_2025_9429_MOESM4_ESM.csv), columns Target, DesignName, Binding; Results prose; Fig. 1b caption

Fig. 1b's caption defines success as binding observed on SPR, but the PD-1 screen was BLI in a bivalent Fc-fusion format and the CLDN1 screen used soluble analogues. The 46.3% average therefore pools targets measured under different endpoints.One-shot design of functional protein binders with BindCraft (Pacesa et al., Nature 2025) · Fig. 1b caption; Results 'Binders targeting cell-surface receptors' and 'Targeting unexplored binding sites'

A source-checked result verifies the numerical transcription, not every model or protocol detail. Evaluation metadata: source checked. Source checked does not mean independently reproduced.

Reproduction

Split: Not reported
Adaptation: Not reported
Scoring implementation: Count of tested designs with an observed binding signal (SPR against full-length apo SpCas9)

No execution recipe has been verified for this exact configuration and evaluation. A benchmark's general instructions may use different inputs, splits or model settings.

Reproducing this published result requires matching its model configuration, data, split and scorer. Source checking or a successful smoke test does not establish score reproduction.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
