A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion.
Ziehl–Neelsen stain (classic and modified bleach types) [5]; Kinyoun stain; For color blind people (or in backgrounds where detecting red bacteria is difficult), Victoria blue can be substituted for carbol fuchsin and picric acid can be used as the counter stain instead of methylene blue, and the rest of the Kinyoun technique can be used.
Numerous naturally-occurring stains exist, such as rust on iron and a patina on bronze, [3] as do accidental stains such as from ketchup and oil on fabrics and other materials. Different types of material can be stained by different substances, and stain resistance is an important characteristic in modern textile engineering. [citation needed]
Carbol fuchsin, carbol-fuchsin, carbolfuchsin, or Castellani's paint (CAS) is a mixture of phenol and basic fuchsin that is used in bacterial staining procedures. It is commonly used in the staining of mycobacteria because it has an affinity for the mycolic acids found in their cell membranes.
To use, spray the stain with the formula and let it sit for up to an hour. It will create a rich lather upon contact on even set-in stains. ... "Unlike other cleaners that have a strong chemical ...
