PATHOLOGY

Detailed explanation-1: -Antibodies are produced by B cells (specialized white blood cells). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells-or plasma cells-release millions of antibodies into your bloodstream and lymph system.

Detailed explanation-2: -The antigen-recognition molecules of B cells are the immunoglobulins, or Ig. These proteins are produced by B cells in a vast range of antigen specificities, each B cell producing immunoglobulin of a single specificity (see Sections 1-8 to 1-10).

Detailed explanation-3: -An antibody (Ab), also known as an immunoglobulin (Ig), is a large protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, called an antigen.

Detailed explanation-4: -Antigens are molecules that initiate the immune response and can be bound by antibodies. Antibodies are proteins produced by B-lymphocytes that bind to specific antigens.
