Main staining types when using hematoxylin and eosin (H&E). Tissues which take up stains are called chromatic. Chromosomes were so named because of their ability to absorb a violet stain. Positive affinity for a specific stain may be designated by the suffix -philic. For example, tissues that stain with an azure stain may be referred to as ...
S. cerevisiae septins revealed with fluorescent microscopy utilizing fluorescent labeling. In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid.
Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]
The staining technique using Giemsa staining is called G banding and therefore produces the typical "G-Bands". [12] A full account of a karyotype may therefore include the number, type, shape and banding of the chromosomes, as well as other cytogenetic information. Variation is often found: between the sexes,
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Cytochemistry is the branch of cell biology dealing with the detection of cell constituents by means of biochemical analysis and visualization techniques. This is the study of the localization of cellular components through the use of staining methods. [ 1 ]
The term "immunostaining" was originally used to refer to the immunohistochemical staining of tissue sections, as first described by Albert Coons in 1941. [1] However, immunostaining now encompasses a broad range of techniques used in histology, cell biology, and molecular biology that use antibody-based staining methods.
