Different wood species stain differently—the overall colour and shade is a result of a combination of the stain and properties of the wood. For example, although medium-to-dark stains tend to look blotchy on maple, they get deeper and more glowing on cherry, with a more consistent colouration. [3]
Hence, proximity of the dye molecules was the key parameter in defining metachromasia. Another example of metachromatic dye (fluorochrome) is acridine orange. Under certain conditions it stains single-stranded nucleic acids fluorescing red (red luminescence) while when interacts with double stranded nucleic acids gives green fluorescence. [1]
Endospore made visible with a stain. Moeller staining involves the use of a steamed dye reagent in order to increase the stainability of endospores. Carbol fuchsin is the primary stain used in this method. Endospores are stained red, while the counterstain methylene blue stains the vegetative bacteria blue.
The material that is trapped coats the underlying material, and the stain reflects backlight according to its own color. Applied paint, spilled food, and wood stains are of this nature. [5] A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types of natural stains fall into ...
In solution with phenol (also called carbolic acid) as an accentuator [16] it is called carbol fuchsin and is used for the Ziehl–Neelsen and other similar acid-fast staining of the mycobacteria which cause tuberculosis, leprosy etc. [17] Basic fuchsine is widely used in biology to stain the nucleus, and is also a component of Lactofuchsin ...
Chlorociboria aeruginascens is a saprobic species of mushroom, commonly known as the blue stain, [1] green elfcup [2] or the green wood cup [3] because of its characteristic small, green, saucer-shaped fruit bodies. Although the actual fruit bodies are infrequently seen, the green staining of wood caused by the fungus is more prevalent.
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
Sap stain fungi on logs in the Bavarian Forest National Park. Blue stain fungi (also known as sap stain fungi) is a vague term including various fungi that cause dark staining in sapwood. [1] The staining is most often blue, but could also be grey or black. Because the grouping is based solely on symptomatics, it is not a monophyletic grouping.
