unusual facts about staining


Zoological specimen

An example would be a vertebrate with an alcohol-preserved skin and viscera, a cleared and stained head, the post-cranial dried skeleton, histological, glass slides of various organs, and frozen tissue samples.


3,3',5,5'-Tetramethylbenzidine

3,3’,5,5’-Tetramethylbenzidine or TMB is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (ELISA).

Baudoinia compniacensis

Baudoinia compniacensis is black in colour and is partly responsible for the frequently observed phenomenon of 'Warehouse Staining', reported originally from the walls of buildings near brandy maturation warehouses in Cognac, France.

Cuisenaire rods

Catherine Stern also devised a set of coloured rods produced by staining wood with aesthetically pleasing colours.

Edward Kravitz

Ed and Tony contacted Imperial Chemicals, a manufacturer of fabric staining dyes located in Providence, RI and obtained over 120 dyes to inject into lobster neurons.

Epithelioid sarcoma

They characteristically have loss of staining for SMARCB1 (INI1, BAF47), and typically stain for CA125.

EuroFlow

Since the '90s immunophenotyping (staining cells with antibodies conjugated with fluorochromes and detection with flow cytometer) became the preferred method in diagnostics of haematological malignancies.

Gastón Guzmán

In 1958, he published his first paper on a blue-staining Psilocybe species and the first paper on the ecology of neurotropic fungi.

Gastrointestinal stromal tumor

--needs tweeking--> as tumors whose behavior is driven by mutations in the Kit gene or PDGFRA gene, and may or may not stain positively for Kit.

George Fowler Jones

John Ward Knowles (about 1845) 'As a youth worked 3–4 months for Jones at Monkgate, but disliked the work and returned to painting and glass staining'.

Glycophorin

A fifth (glycophorin E) has been identified within the human genome but cannot easily be detected on routine gel staining.

Grocott

Grocott's methenamine silver stain, abbreviated GMS, a popular staining method in histology

Heinrich Wilhelm Gottfried von Waldeyer-Hartz

Waldeyer used the path-breaking discoveries by neuroanatomists (and later Nobel Prize winners) Camillo Golgi (1843–1926) and Santiago Ramón y Cajal (1852–1934), who had used the silver nitrate method of staining nerve tissue (Golgi's method) to formulate a short brilliant synthesis, even though he did not contribute with any original observations.

Inocybe erubescens

The red-staining inocybe was first described by Axel Gudbrand Blytt in 1904 as Inocybe erubescens, though was widely known for many years as I.

Polymer characterization

Transmission Electron Microscopy in combination with staining techniques, but also Scanning Electron Microscopy, Scanning probe microscopy are important tools to optimize the morphology of materials like polybutadiene-polystyrene polymers and many polymer blends.

Sentinel lymph node

Then, during the biopsy, the physician visually inspects the lymph nodes for staining and uses a gamma probe or a Geiger counter to assess which lymph nodes have taken up the radionuclide.

Supravital staining

Supravital staining can be combined with cell surface antibody staining (immunofluorescence) for applications such as FACS analysis.

Two-dimensional gel electrophoresis

These proteins can then be detected by a variety of means, but the most commonly used stains are silver and Coomassie Brilliant Blue staining.

Ziehl–Neelsen stain

A variation on this staining method is used in mycology to differentially stain acid-fast incrustations in the cuticular hyphae of certain species of fungi in the genus Russula.
