Compare two measurements
Choose two records and the server checks whether they can be compared: identity, endpoint, value, assay, conditions, molecular form, dependence, direction, evidence class and sources. When a rule fails, the result names it and what would be needed.
Choose two records
Rehearse the rules with invented examples
Strictly matched metadataAll required identity, endpoint, condition, molecule and provenance fields match.Endpoint mismatchA Ki record and an IC50 record must remain distinct.Condition mismatchThe pH differs even though the other fixture fields match.Construct mismatchCanonical full-length and truncated constructs cannot be ranked as one target state.
These examples use invented metadata to show how the rules decide. They are not evidence and carry no scientific values or citations.
These cannot be compared
Construct mismatch: Canonical full-length and truncated constructs cannot be ranked as one target state.

VARIANT_OR_CONSTRUCT_MISMATCHvariant, construct
The variant or experimental construct differs.
Needed: Match sequence variant, truncation, fusion and tag state.How the rules work
- Compare only exact, versioned protein identities; names are not identifiers.
- Rank quantitative measurements only within one assay or an independently reviewed matched-protocol group.
- Keep Ki, Kd, IC50, EC50, Km, kcat and kcat/Km as separate endpoint types.
- Preserve source relation operators and raw values; a bound is not a point estimate.
- Keep experimental constructs, variants, tested molecular forms and conditions explicit.
- Display a refusal with actionable reasons whenever strict comparison requirements are not met.
