Different stains have been developed over time to distinguish bacteria species, separating them morphologically and the specific characteristics they possess. The most popular stain is Gram staining, acid-fast staining, and endospore staining. Each stain aims at identifying and defining bacteria according to their forms and morphologies.
Different stains react or concentrate on different areas of a tissue or cell These properties can be utilized to highlight certain areas or regions. A few of the most well-known biological staining methods can be found below. If not otherwise indicated All of these dyes can be used on tissues and cells that are fixed as well as essential dyes (suitable for use in live organisms) are indicated.
Staining is a method used to boost the contrast of samples, usually at the microscopic scale.
This stain was discovered by German chemist Gustav Giemsa, that’s why its called Wright Giemsa Stain.
Immunological techniques is the set of laboratory methods that is based on the specific antigen–antibody reaction, and it is used to detect, identify or measure different biological substances in a sample. It is the process where an antibody binds with its corresponding antigen and this binding is used for locating proteins, hormones, pathogens or other … Read more
Immunoelectrophoresis (IEP) is the process in which proteins of a biological sample are first separated by electrophoresis and then allowed to react with specific antibodies inside a gel. It is the technique combining electrophoresis with immunodiffusion. In this method the sample like serum is placed on an agarose gel and an electric field is applied, … Read more
What is Production Media? Production media is the nutrient-rich medium used to support the large-scale growth of microorganisms or cell cultures for the purpose of producing useful biological substances. It is designed in such a way that optimum growth conditions is maintained, and the metabolic activities of the organisms is supported for yielding products like … Read more
Northern blotting or Northern hybridization is a widely used technique in molecular biology to determine the molecular weight of mRNA and to measure relative amounts of mRNA present in different samples and for identifying alternatively spliced transcripts and multigene family members.
Protochordate larvae is the juvenile stage found in lower chordates, and it is seen in members of Urochordata and Cephalochordata. It is the stage where the animal shows the typical chordate features very clearly. It is the notochord, dorsal hollow nerve cord, pharyngeal slits, and the post-anal tail that appear in this larval period. It … Read more
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
