In this article we will discuss about the structure of antibody with the help of suitable diagram. Also learn about the production of monoclonal antibodies. The chemical substance produced by the body against the antigen is called antibody. Antibodies belong to a group referred to as gamma globulins and are called immuno globulins. They have molecular weight between 160,000 and [...]

Cell Mediated Immune Response: Cell mediated immune response is carried out by the T-cells or T lymphocytes (Fig. 11). So, it is also called T-cell immunity.

1. Light: Light is the most important and indispensable physicochemical, abiotic ecological factor without which life cannot exist. Organisms get light from the Sun, Moon, stars, lightning, volcanoes and bioluminescent organisms. Among this light energy from the Sun is the most important in nearly all ecosystems. It is the energy that is used by green plants (which contain chlorophyll) during [...]
