[Specific complex formation study of human immunoglobulins of various classes with their antibodies]
The process of specific complex formation of different human immunoglobulines M, G and A with IgG antibody against them was investigated by the thermistor method. It was shown that the rate and intensity of the process vary with the types of interacting immunoglobulines, and that they reach maximum for IgM. From the character of the curves obtained a judgement can be formed about the immunoglobulin type being synthesized at the given moment. Disturbance of the inner structure of immunoglobulin macromolecules, e.g. during heating, leads to changes in the mechanism of complex formation, it being important what particular component underwent denaturation.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
Antibody Actions
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...
