  2. Gram stain - Wikipedia

    en.wikipedia.org/wiki/Gram_stain

    They are stained pink or red by the counterstain, [3] commonly safranin or fuchsine. Lugol's iodine solution is always added after addition of crystal violet to form a stable complex with crystal violet that strengthen the bonds of the stain with the cell wall. [4] Gram staining is almost always the first step in the identification of a ...

  3. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing microbiologists to select appropriate tests to provide a definitive ...

  4. Morphology (biology) - Wikipedia

    en.wikipedia.org/wiki/Morphology_(biology)

    Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...

  5. H&E stain - Wikipedia

    en.wikipedia.org/wiki/H&E_stain

    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]

    Depression ware Pink sunflower patterned depression cake plate Green patterned Depression glass pieces. Depression glass is glassware made in the period 1929–1939, often clear or colored translucent machine-made glassware that was distributed free, or at low cost, in the United States and Canada around the time of the Great Depression.

  7. Endospore staining - Wikipedia

    en.wikipedia.org/wiki/Endospore_staining

    Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [ 2 ]

  8. PINK1 - Wikipedia

    en.wikipedia.org/wiki/PINK1

    PINK1 is synthesized as a 63000 Da protein which is often cleaved by PARL, between the 103-Alanine and the 104-Phenylalanine residues, into a 53000 Da fragment. [11] PINK1 contains an N-terminal mitochondrial localization sequence, a putative transmembrane sequence, a Ser/Thr kinase domain, and a C-terminal regulatory sequence.

  9. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    In vivo staining (also called vital staining or intravital staining) is the process of dyeing living tissues. By causing certain cells or structures to take on contrasting colours, their form or position within a cell or tissue can be readily seen and studied.
