Intact Protein Characterization Evidence and Material Handoff

INTACT PROTEIN CHARACTERIZATION · RESEARCH USE ONLY
An evidence workspace that does not collapse mass, separation, and migration into one conclusion
Record material lineage, class-specific observations, provenance, human review, and the Bottom-up handoff separately. The product does not parse raw files or automatically claim protein identity, purity, oligomer state, or activity.
Research Use Only. This product does not certify release, clinical or regulatory suitability, or analytical success.
- 1. Material lineage
- 2. Assay class
- 3. Provenance
- 4. Observation & review
- 5. Material handoff
Locked interpretation boundaries
- MS neutral/assembly mass and m/z remain different quantities.
- SEC-UV retention is never converted to molecular mass.
- Native-gel migration is not exact mass or stoichiometry.
- T0/T1/T2 describes record depth, not sample quality.
Displaying declared reference mass beside observed mass is not a match, identity, or proteoform assignment.
Consistency among comparable observations is not identity, oligomer, purity, or orthogonal confirmation.
Locked interpretation boundaries
MS neutral/assembly mass and m/z remain different quantities. SEC-UV retention is never converted to molecular mass. Native-gel migration is not exact mass or stoichiometry. T0/T1/T2 describes record depth, not sample quality.
1. DEFINE MATERIAL LINEAGE AND INTENDED CONSUMER
Create one parent-lot identity and explicit characterized and downstream aliquot states. Record material role, research purpose, current form, current matrix, concentration provenance, remaining material, treatment history, and every unresolved unknown before interpreting evidence.
2. SELECT ONE CLOSED EVIDENCE CLASS PER ASSAY
Choose denaturing intact MS, native MS, relative SEC-UV, SEC-MALS, or relative native gel according to the actual source and observation type. Unsupported methods route to OTHER_HELD and are never coerced into the nearest registered class.
3. RECORD ACQUISITION AND TRANSFORMATION PROVENANCE
For each assay, identify specimen aliquot, pre- and post-assay state, operation class, covalent treatment, solution intent, instrument, acquisition run, software revision, source profile, artifacts, and every processing edge.
4. ENTER CLASS-SPECIFIC OBSERVATIONS WITHOUT INFERENCE
Record only the observation union supported by the selected class: neutral or assembly mass with its declared basis, source-reported m/z, SEC retention and relative signal, source-reported SEC-MALS molar mass, or relative native-gel migration.
5. PRESERVE EXCLUSIONS, CONFLICTS, AND UNKNOWNS
Keep excluded observations and artifacts addressable with reasons. Record incompatible or incomplete cross-assay comparisons as conflicting, insufficient, or not comparable instead of selecting, averaging, or normalizing them silently.
6. REVIEW EVIDENCE TIER SEPARATELY FROM MATERIAL READINESS
Recompute T0, T1, or T2 only from the closed evidence record and explicit cross-assay review. Evidence tier is documentation depth, not sample quality, identity, release suitability, or downstream readiness.
7. EVALUATE THE BOTTOM-UP MATERIAL HANDOFF
Review same-aliquot, sibling-aliquot, or collected-fraction lineage; state-changing operations; sibling applicability; fraction identity; concentration measurement; current matrix; remaining volume; and blocking unknowns before creating a typed producer receipt.
8. EXPORT AN EVALUATED RESEARCH RECORD
Export the parsed and evaluated typed record, source identities, evidence summary, exclusions, conflicts, unknowns, handoff status, and immutable limitations through the shared ProtocolCore DOCX/XLSX model.
