What it is Filled
A laboratory technique that applies dyes, pigments, metals or labelled molecules to biological specimens so that cells, tissues, organisms or molecules become visible or distinguishable under a microscope, including histological stains such as haematoxylin and eosin, special stains such as acid-fast and Luxol fast blue, silver methods such as Ag-NOR staining, and immunostaining and fluorescence staining with antibodies and probes.
Why it exists Filled
Let an agent explain staining as a technique, identify kinds and their targets, relay protocols and standards in general terms from laboratory references, and distinguish staining from other visualisation methods.
Distinguishing features Filled
- Contrast by binding
- Specific and general stains
- Diagnostic and research use
- Standardised protocols
What robots and AI may and may not do Filled
Must not
- Report a diagnosis from a stained slide without review by a qualified pathologist.
- Run staining without positive and negative controls when results are used clinically.
- Dispose of toxic staining reagents down the drain.
- Alter images of stained specimens without disclosure.
Only with a human decision
- Releasing a clinical result based on staining.
May
- Describe staining techniques and what each reveals in a specimen.
- Record stain batches, controls and protocols in a laboratory information system it is authorized to use.
- Flag possible artefacts in a stained slide for review by a qualified person.
Moral aspects Filled
- Stains guide cancer and infection diagnoses; false results harm patients.
- Some reagents are toxic to laboratory staff and the environment.
Who is affected
- Patients
- Laboratory staff
- Researchers

Plane ACT: no invented physical properties.
Recognition optional Filled
- Dye, metal or label applied to specimens for contrast
- Histological, microbiological, immuno and fluorescence stains

- Coloured or fluorescent specimens on slides, viewed under a microscope.
Capabilities and actions required Filled
- explain principles and kinds
- identify stains and their targets
- relay standards and quality control
- distinguish from other methods
Hazards and failure modes required Filled
- Artefacts and false results
- Toxic reagents
- Batch variation without controls
Standards and interfaces required Filled
- Laboratory accreditation standards such as ISO 15189
- Quality control schemes for histology and immunohistochemistry
- Chemical safety for dyes and fixatives
Context of use required Filled
- Making biological structures visible for microscopy and diagnosis.
- general histological stains such as haematoxylin and eosin
- special stains such as acid-fast, PAS and Luxol fast blue
- silver and metal stains such as Ag-NOR
- microbiological stains such as Gram stain
- immunostaining and immunohistochemistry
- fluorescence staining and live-cell dyes

Open questions
- Should immunostaining and each classic stain be separate entries?
- How should protocol references be linked?
- The registry entry has merged aliases naming specific stains; should they be split off?
