Iron-Hematoxylin Staining – Principle, Procedure, Uses
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 Staining – Principle, Procedure, Uses
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 Staining – Principle, Procedure, Uses
Collagen Hybridizing Peptide stain is a vital stain used for the detection of collagen degraded tissues, mainly used in Developmental Biology, Histology, and Histopathology.
Parasporal Crystal Stain – Principle, Procedure, Result
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 – Definition, Procedure, Principle, Advantages, Limitation, Uses
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 Blot – Definition, Principle, Steps, Importance
Southern Blotting is a molecular biology technique used for the identification of a specific DNA sequence in a collected DNA sample.
Gerhardt’s test – Principle, Procedure, Result
Gerhardt’s test is a type of laboratory test which is performed for the qualitative detection of ketone bodies in urine.
Widal Test – Principle, Procedure, Result, Advantages, Limitation
The Widal test is an agglutination test that determines any antibodies present in the patient’s serum that are generated against the causal agents of the enteric febrile illness (Salmonella Typhi, and Salmonella paratyphi B, A as well as C).
Counter Current Immunoelectrophoresis – Principle, Procedure, Result.
Counter current immunoelectrophoresis is a modification of immunoelectrophoresis in which antigen and antibody migrate towards opposite directions and form a visible white precipitate in the area between the wells.
