Agglutination- Introduction and Applications

Agglutination- Introduction and Applications

Agglutination- Introduction and Applications Agglutination is an antigen-antibody reaction in which a particulate antigen combines with its antibody in the presence of electrolytes at a specified temperature and pH resulting in the formation of visible clumping of particles. Agglutination occurs optimally when antigens and antibodies react in equivalent proportions. This reaction is analogous to the … Read moreAgglutination- Introduction and Applications

Types of Precipitation Reactions

Types of Precipitation Reactions

Types of Precipitation Reactions Precipitation reactions can be broadly of three types: Precipitation in solution. Precipitation in agar. Precipitation in agar with an electric field. Precipitation in solution Ring test and flocculation test are examples of precipitation in solution. It is also called simple precipitation. Ring test: In this test a clear solution of test … Read moreTypes of Precipitation Reactions

Introduction to Precipitation Reaction

Introduction to Precipitation Reaction

Introduction to Precipitation Reaction It is a type of antigen–antibody reaction, in which the antigen occurs in a soluble form. When a soluble antigen reacts with its specific antibody, at an optimum temperature and PH in the presence of electrolyte antigen antibody complex forms insoluble precipitate. This reaction is called precipitation reaction. A lattice is … Read moreIntroduction to Precipitation Reaction

Introduction to Antigen-Antibody Reactions

Introduction to Antigen-Antibody Reactions

Introduction to Antigen-Antibody Reactions The interactions between antigens and antibodies are known as antigen–antibody reactions. The reactions are highly specific, and an antigen reacts only with antibodies produced by itself or with closely related antigens. Antibodies recognize molecular shapes (epitopes) on antigens. Generally, the better the fit of the epitope (in terms of geometry and … Read moreIntroduction to Antigen-Antibody Reactions

Properties and Function of different classes of Antibodies

Properties and Function of different classes of Antibodies

Properties and Function of different classes of Antibodies Antibodies are glycoproteins produced in membrane-bound or secreted form by B lymphocytes in response to exposure to foreign structures known as antigens. The human immunoglobulins are a family of proteins that confer humoral immunity and perform vital roles in promoting cellular immunity. There are five classes of … Read moreProperties and Function of different classes of Antibodies

Antibody- Introduction, Structure and Classes

Antibody- Structure-and-Classes

Antibody- Introduction, Structure and Classes Antibodies are often referred to as immunoglobulins (immune proteins).  Antibodies, or Y-shaped immunoglobulins, are proteins found in the blood that help to fight against foreign substances called antigens. Antigens, which are usually proteins or polysaccharides, stimulate the immune system to produce antibodies. The antibodies inactivate the antigen and help to remove … Read moreAntibody- Introduction, Structure and Classes
