Structure of Antibodies Essay

Introduction
There are a lot of antibodies in our body. However, we seem not too much about it. We just simply remember that it is Y shape structure and it can fight the antigens. Therefore, we want to look more deeply about this topic to know how antibody can be produced and how it can produce a large number of antibodies. In this study, we will review the antibodies in different areas: Structure of antibody, ways of affecting the diversity of antibodies and mechanisms for generate antibodies and how to let it be specific. Moreover, we have a future direction for antibody technology development to talk a little bit for this area.

Structure of antibodies
As we all known that antibody is a type of protein with Y shape structure. It consists of two heavy chains and light chains (Roderick and Matthew, 2007). There are two types of light chains, which one is called Kappa and other is Lambda (Roderick, 2007). Both heavy and light chains connect with each other by using disulfide bonds. The function of hinge region can let antibodies become more fexible. Both heavy and light chain have variable region and constant region, variable region can give the specificity for binding antigen; while constant region (also name as isotype region) is determined the mechanism for destroy antigen, and guess the infection time by define the region of constant region of antibodies. As stated on USCSM(2010), hyper-variable region and framework region are similar meaning of the variable region and
