Flashcards: Staining

Basophilia is a condition where the basophil quantity is abnormally elevated (more than 1010 basophils per liter of blood).

The green fluorescent protein (GFP) is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range.

Gram staining, also called Gram's method, is a method of staining used to differentiate bacterial species into two large groups (gram-positive and gram-negative).

An azurophilic granule is a cellular object readily stainable with a Romanowsky stain.

Thionine, also known as thionine acetate or Lauth's violet, is a strongly staining metachromatic dye, featuring a phenothiazine core, that is widely used for biological staining.

Alcian blue or alcian blue (/ˈælʃən/) is any member of a family of polyvalent basic dyes, of which the Alcian blue 8G (also called Ingrain blue 1, and C.I. 74240, formerly called Alcian blue 8GX from the name of a batch of an ICI product) has been historically the most common and the most reliable member.

Phosphotungstic acid (PTA), tungstophosphoric acid (TPA), is a heteropoly acid with the chemical formula H3PW12O40.

Biebrich scarlet (C.I. 26905) is a molecule used in Lillie's trichrome.

A chromophobe is a histological structure that does not stain readily, and thus appears relatively pale under the microscope.

Trichrome, meaning "three colour" was used as the name of a staining method (Mallory's trichrome) which differentially coloured erythrocytes orange, muscle red and collagen blue.

Cresyl violet is an organic compound with the chemical formula C19H18ClN3O.
