Immunoglobulins, also known as antibodies, are glycoprotein molecules produced by plasma cells in response to antigens. They function to bind to antigens and activate effector functions like complement fixation and binding to cells. The basic immunoglobulin structure consists of two heavy chains and two light chains held together by disulfide bonds. The variable regions at the tips of the molecules give immunoglobulins their specificity for different antigens. There are five major classes of human immunoglobulins - IgG, IgM, IgA, IgD, and IgE - which have different structures and functions.
Antibody(Ab) or immunoglobulin(Ig) is the large Y shaped glycoprotein produced by the body’s immune system when it detects harmful substances are called antigens.
They are synthesized by B lymphocytes and secreted by plasma cells.
Depending on the electrophoretic migration, 3 types of globulins are present in the blood, namely α, β and γ
So antibodies are gamma (γ) globulin.

Adaptive/Acquired Immunity
Antigens – Anything that cases a biological immune response by this system of cells
Specificity – Some antibodies are quite specific to an antigen others are general to a “type” or “form”
Memory – b-memory cells are formed and remain to combat future exposures quickly (Active vs Passive immunity
Antibodies – the proteins formed by b-cells that combat antigens whether chemical or biological
Lymphocytes – cells involved in this response
The Immune Response
Immunity: “Free from burden”. Ability of an organism to recognize and defend itself against specific pathogens or antigens.
Immune Response: Third line of defense. Involves production of antibodies and generation of specialized lymphocytes against specific antigens.
Antigen: Molecules from a pathogen or foreign organism that provoke a specific immune response
Antibodies are immune system-related proteins called immunoglobulins. Each antibody consists of four polypeptides– two heavy chains and two light chains joined to form a "Y" shaped molecule. ... This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen.
This is a brief presentation on the topic Cell Mediated Immunity describing how our immune system gets activated in response to any xenobiotic which is different from the mechanism followed by humoral immunity.

Describes the complement system components and their activation pathways, the regulation of the complement
system, the effector functions of various complement components,
and the consequences of deficiencies in them.
Immunology is the study of the immune system and is a very important branch of the medical and biological sciences. The immune system protects us from infection through
