The Biological Stain commission is an independent non-profit company that has been testing dyes since the early 1920s and issuing Certificates of approval for batches of dyes that meet internationally recognized standards. StainsFile Reference for dyes and staining techniques.
The Biological Stain ... These have included studies of many classical and modern staining techniques (see Gray 1954. ... of dyes and other colorants in biology and ...
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.
Histologic specimen being placed on the stage of an optical microscope. Human lung tissue stained with hematoxylin and eosin as seen under a microscope.. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
This process is called staining, which can be used to prepare botanical specimens so that it is possible to distinguish one part of the sample from another in terms of color. [2] Acid dyes can be used when staining micro slides, for example, acid dyes are in use when coloring nuclei and other cellular components are stained using alkaline. [2]
The above techniques can be combined with computational methods to estimate staining levels without staining the cell. These approaches, generally, rely on training a deep-convolutional neural network to perform imaging remapping, converting the bright-field or phase image into a fluorescent image.
Biology portal; To get a detailed description of the various methods see protein methods and nucleic acid methods. Besides the aforementioned groups of techniques, biotechnology also includes plant tissue culture methods, animal cell culture methods, and microbial fermentation methods.
Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.
