Definition of Anisocytosis Anisocytosis is a condition in which the diameters of erythrocytes (red blood cells) are uneven. The term “aniso” means unequal, while “cytosis” means cell movement or quantity. Excessive red blood cell size variation, known as anisocytosis, can be quantified by peripheral blood film analysis as well as automated red blood cell size … Read more
Endospore Staining-Introduction A vegetative form of a bacterial cell is a normal bacterial cell. It may multiply indefinitely if given favourable environmental circumstances like as nutrients, temperature, water, as well as oxygen. However, when exposed to unfavourable situations like a lack of nutrients, an inadequate supply of oxygen or CO2, absence of water as well … Read more
Flow Cytometry – What is it? For the detection and measurement of physical and chemical properties of cells or particles in heterogeneous fluid mixtures, flow cytometry is commonly used with laser-based technology. This technique has gained in popularity over time since it provides for a fast examination of various cell characteristics (including qualitative and quantitative). … Read more
What Is Northern Blot? For the study of RNA in complicated mixtures, Northern blot is a technique that relies on the notion of “blotting”. Essentially, it is a modified version of the Southern Blotting technique, which was originally developed for the examination of DNA sequences. Molecular biology requires the detection of certain sequences of nucleic … Read more
What is MPV in Blood Test? The MPV (Mean Platelet Volume) test is used to assess the average size of platelets in a blood sample. Platelets are vital blood cells that are in charge of blood clotting, a process which regulates blood loss after an injury. The mean platelet volume (MPV) is a measurement of … Read more
Latex Agglutination Test Electrolytes, at the appropriate temperature and pH, are added to a particulate or insoluble antigen to cause it to clump. There are three types of agglutination reactions: direct, indirect (passive), and reverse passive. Adhesion Tests are those in which the antigen agglutinates with an antibody directly. It includes coating an antigen upon … Read more
Iodine Test Definition The iodine test is a chemical method for separating mono- as well as disaccharides from polysaccharides such as amylase, dextrin as well as glycogen. The starch-iodine test is a version of this test which is used to test the existence of glucose produced by plants in the leaves. Iodine Test Objectives Existence … Read more
Eosin Methylene Blue (EMB) Agar Eosin Methylene Blue (EMB) agar is a microbiological selective stain that limits Gram-positive bacteria’s growth while simultaneously serving as a colour indication for identifying organisms which help ferment lactose (e.g., E. coli) even those who don’t (e.g., E. coli) (e.g., Salmonella, Shigella). EMB agar was invented by Holt-Harris and Teague, … Read more
What is the Purpose of the Biuret Test? Proteins are made up of hundreds of amino acids and are a complicated substance. Amino acids are amphoteric electrolytes that include carboxyl and amino groups, respectively, and act as an acid and a base. These ions are electrically neutral and do not migrate in the electric field … Read more
What is Streak Plate Method ? Striking (Streak Plate Method) is a microbiology technique for isolating a pure strain from a single species of microbe, most commonly bacteria. Loeffler and Gaffky invented the dilution or isolation by streaking method in Koch’s laboratory, which includes systematically streaking bacteria across the exterior of the agar in a … Read more
