  2. Endospore - Wikipedia

    en.wikipedia.org/wiki/Endospore

    An endospore is a dormant, ... However, after further studies this group concluded that the structure of the spore coat protein was different from keratin. [12]

  3. 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 ]

  4. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    Bacterial spores have proven to be difficult to stain as they are not permeable to aqueous dye reagents. Endospore staining is particularly useful for identifying endospore-forming bacterial pathogens such as Clostridioides difficile. Prior to the development of more efficient methods, this stain was performed using the Wirtz method with heat ...

  6. Keratin - Wikipedia

    en.wikipedia.org/wiki/Keratin

    Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents.

  9. Keratohyalin - Wikipedia

    en.wikipedia.org/wiki/Keratohyalin

    Keratohyalin is a protein structure found in cytoplasmic granules of the keratinocytes in the stratum granulosum of the epidermis.Keratohyalin granules (KHG) mainly consist of keratin, profilaggrin, [1] loricrin [2] and trichohyalin proteins which contribute to cornification or keratinization, the process of the formation of epidermal cornified cell envelope.
