Of what type of protein are antibody molecules made.
Phage display recombinant monoclonal antibodies are expressed when DNA sequences encoding an antibody's variable regions are fused with a bacteriophage's genes that encode the coat protein. Thus, the phage's coat expresses an antibody fusion protein on its surface. Benefits: Lot-to-lot consistency due to recombinant production
The function of antibodies (Abs) involves specific binding to antigens (Ags) and activation of other components of the immune system to fight pathogens.

Antibody Structure. An antibody has a Y-shaped structure, made up of four polypeptide subunits. Each subunit has two identical light and heavy chains. The N-terminus of each heavy chain forms an antigen-binding domain with a light chain. There are two antigen-binding domains forming the arms of the “Y” shape. IgM consists of five four-chain structures (20 total chains with 10 identical antigen-binding sites) and is thus the largest of the antibody molecules. IgM is usually the first antibody made during a primary response. Its 10 antigen-binding sites and large shape allow it to bind well to many bacterial surfaces.A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells..

Small proteins may contain just a few hundred amino acids, whereas large proteins may contain thousands of amino acids.An antibody is defined as “an immunoglobulin capable of specific combination with the antigen that caused its production in a susceptible animal.”. Antibodies are produced in response to the invasion of foreign molecules in the body. An antibody, abbreviated as Ab, is commonly referred to as an immunoglobulin or Ig.The immune system forms antibodies against whichever ABO blood group antigens are not found on the individual's RBCs.
