Agglutination Test – definition, Types, Uses, Advantages, Disadvantages

Toolmakers Microscope - Principle, Procedure, Parts, Applications

Agglutination test is an immunological and serological test which is used to detect specific antigen or antibody in the patient sample. It is based on the visible clumping reaction between particulate antigen and its specific antibody. In this reaction, antibody binds with more than one antigen particle and form a lattice like network. So the … Read more

Types of Immunoelectrophoresis Techniques

Types of Immunoelectrophoresis 

Immunoelectrophoresis is a biochemical technique which is used for the separation and identification of proteins, mainly immunoglobulins in biological samples. It is a combined method of electrophoresis and immunodiffusion. In this technique, proteins are first separated in agarose gel by applying electric current. After separation, specific antibody is added into the gel. The separated proteins … Read more

15 Types of Immunological Techniques With Examples

Different Types of Immunological Techniques With Examples

Immunological techniques are laboratory methods which are used to detect and measure different substances present in the body. It is mainly based on the specific reaction between antigen and antibody. Antigen is a substance which can produce immune response in the body. Antibody is a protein molecule produced by immune system against that specific antigen. … Read more

Active Immunization - Definition, Mechanism, Advantages, Disadvantages, Examples

Active immunization is the process by which body own immune system is stimulated by giving antigen or vaccine. It produce antibodies and memory cells. The immunity is slow but long lasting. Active immunization is the process by which a harmless antigen is introduced into the body to produce immune response. It is commonly done by … Read more

Immunoglobulin A (IgA Antibody) – Structure, Subclasses and Functions

Immunoglobulin A (IgA Antibody) - Structure, Subclasses and Functions

Immunoglobulin A (IgA) is a type of antibody which is produced by plasma cells. It is mainly present in external secretion of body. It gives first protection in mucosal surface. It is found in saliva, tears, breast milk, respiratory tract secretion, gastrointestinal tract secretion and genitourinary tract secretion. So IgA is the major antibody of … Read more

Mucosa Associated Lymphoid Tissues (MALT) – Definition, Features, Structure, Functions

Mucosa Associated Lymphoid Tissues (MALT) - Definition, Features, Structure, Functions and Examples

Mucosa Associated Lymphoid Tissue (MALT) is a lymphoid tissue present in mucosal and submucosal lining of body. It protects mucosal surfaces from harmful antigen and microbes entering through digestive, respiratory and other tracts. Mucosa Associated Lymphoid Tissue (MALT) is a specialized lymphoid tissue present in the mucosal and submucosal lining of body. It is not … Read more

Immunoglobulin M (IgM Antibody) – Definition, Structure, Functions

Immunoglobulin M (IgM Antibody) - Definition, Structure, Functions

Immunoglobulin M (IgM Antibody) is a type of antibody that is produced by plasma cells during early immune response. It is the first antibody formed when any foreign antigen enters into the body. It acts as an important first line defence of the immune system. IgM is considered as the most ancient immunoglobulin of adaptive … Read more
