What is Hematoxylin Stain(Gill)? Hematoxylin stain (use with Eosin stain) is mainly used to display the general morphological structure of normal components and lesions of various tissues, and comprehensive observation. H-E Stain is an essential basic staining method in biology, histology, pathology and cytology. It is widely used in pathological diagnosis, teaching and scientific research and has important value. The nucleus in the cell is composed of an acidic substance,

Testing Principle Brucella is a Gram-negative small coccobacillus, typically stained using the Kozlowski staining method (Korotkoff stain). Brucella has a high affinity for safranin dye, and once stained, it is not easily counterstained by other dyes. Therefore, this kit uses safranin to stain Brucella, while employing a blue counterstain to contrast other bacteria and cells. Stain Results Brucella appears red, while other bacteria and cells are displayed in blue or gray-blue

What is Fungal Fluorescence Stain (Two-steps method) ? Fluorescent brightener is a kind of fluorescent dye. It has strong affinity with chitin and cellulose of fungal cell wall. Under ultraviolet light (wavelength: 340-380nm), it will emit bright blue fluorescence. Therefore, the morphology was observed by a fluorescence microscope to qualitatively detect the fungus. Stain Results The mycelia and spores of the fungus were all bright blue, and the structure was clear and

Fungal Stain (Hexamine silver method) Baso Clear Colourful Stains Testing Principle After the specimen is oxidized with periodic acid, the mucopolysaccharide in the cell wall of fungi and other opportunistic organisms exposes aldehyde groups, which reduce silver hexamine to black metallic silver. Sodium thiosulfate fixes the colored silver salt and removes unreacted silver ions. Stain Results The mycelia and spores of the fungus are brown-black or black, the structure is

WeakAcid Fast Stain 4x250ml Baso Clear Colourful Stains for Healthcare Facility Testing Principle Acid-fast bacteria such as Mycobacterium tuberculosis and Mycobacterium leprae are difficult to stain because of their lipoid capsule in the cell wall. However, once the lipoid capsule is stained with an enhanced dye such as carbolfuchsin, the newly formed compound will resist decolorization from acid-alcohol and retain the original color stained (red), which can be easily

Testing Principle Acid-fast bacteria such as Mycobacterium tuberculosis and Mycobacterium leprae are difficult to stain because of their lipoid capsule in the cell wall. However, once the lipoid capsule is stained with an enhanced dye such as carbolfuchsin, the newly formed compound will resist decolorization from acid-alcohol and retain the original color stained (red), which can be easily differentiated from other microorganisms that still adsorb the counter blue stain.

Flagella Stain Principle: Flagellum is a locomotory appendage responsible formotility of most motile bacteria of certain taxonomic groups. It can be observed under electron microscopy, or coated with stain until it is thick enough to be seen under light microscope. Examining the number and location of bacteria flagella is a popular method for identifying bacteria.

Metachromatic Granules Stain Principle: The size of Corynebacterium diphtheriae is very variable, essentially rod-shaped but often showing irregular expansion at one end. Cells frequently lie in small clusters at acute angles to each other in V, L or Y shapes. Gram positive but readily decolorized, non-motile, non-capsulate, non-sporing. Strains are distributed as beans and stained unevenly. With Metachromatic Granules Stain, deeply stained granules known as metachromatic

Bacterial Capsule Stain Principle: Capsule is a characteristic mucous substance developed external to but contagious with the cell wall during bacteria's life cycle. The capsule can protect bacteria from phagocytosis and subsequent digestion by their host, thus increasing their infectivity. Capsules can only be stained with certain special stains. Identification of capsules is very important for bacteria grouping and differentiation. Specifications: Contents 2vials×20ml/Kit

Bacterial Spore Stain Principle: Bacterial spores are the resting state of bacteria. They can resist various physical and chemical factors and endure execrable conditions. Spores, which have strong refraction, can be observed under light microscope when properly stained. Baso Spore Stain is a very useful tool for bacteria differentiation that allows the identification of size, shape and location of bacterial spores. Specifications: Contents 3vials×20ml/Kit Components
