Cell membrane staining is the process in which the plasma membrane of a cell is visualized with the help of dyes or fluorescent probes. It is the thin outer covering of the cell, and it is normally transparent, so it cannot be seen clearly under a simple light microscope. It is the process where special … Read more
Giemsa stain is a polychromatic nucleic acid stain that is used mainly for demonstrating different blood cells and parasites in stained blood films.

Hematoxylin is extracted from a leguminous plant, known as Haematoxylon campechianum, thus it is a natural dye. It forms hematein by oxidation (Ripening).
Acridine Orange contains metachromatic properties, that’s why it is employed in fluorescence microscopy and flow cytometry study of cellular physiology and cell cycle state, including the fluorescent microscopic examination of microorganisms.
Collagen Hybridizing Peptide stain is a vital stain used for the detection of collagen degraded tissues, mainly used in Developmental Biology, Histology, and Histopathology.
Production of parasporal crystals is a unique ability (among Bacillus species) of Bacillus thuringiensis. This stain is a means of rapid identification of the species.
Latex agglutination test is a simple serological test where antigen and antibody reaction is made visible on the surface of latex particles. It is the process in which latex beads are coated either with antigen or with antibody and when a sample containing the corresponding component is added, the beads is clumped together forming visible … Read more
Southern Blotting is a molecular biology technique used for the identification of a specific DNA sequence in a collected DNA sample.
