Establish a traceable chain of scientific evidence and inquiry checklist, from candidate biomarker discovery, sample pre-processing, and analytical method selection to multi-platform validation.
Core Research Questions
- Do candidate biomarkers have clear biological basis and measurable range?
- Do sample collection, storage, and freeze-thaw cycles affect analytical results?
- Can antibodies, primers, or standards meet specificity and dynamic range requirements?
- Can tissue, cell, and body fluid results be validated by orthogonal and independent cohorts?
Common Samples & Models
- Serum, plasma, urine, cerebrospinal fluid, and other bodily fluids
- Fresh, frozen, or FFPE tissues
- Cells, culture supernatants, nucleic acids, and protein extracts
Key Mechanisms & Observation Dimensions

Solution Design & Quality Requirements
It is recommended to pre-define research hypotheses, primary endpoints, negative and positive controls, biological replicates, exclusion criteria, and statistical methods. Different samples, species, platforms, and batches require independent compatibility confirmation, and original data, reagent lot numbers, and key operational records must be retained.
