Goodsell shows part of a red blood cell, in ...Antigen receptor molecules are proteins, which are composed of a few polypeptide chains (i.e., chains of amino acids linked together by chemical bonds known as peptide bonds). The sequence in which the amino acids are assembled to form a particular polypeptide chain is specified by a discrete region of DNA , called a gene .

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.

Antibodies are usually obtained from rats or rabbits. If the antibody is obtained from camelids, a unique antibody protein known as a single-chain antibody or nanobody can be obtained [3,4]. A typical antibody usually consists of four polypeptide chains per molecule, whereas a camelid antibody has two chains per antibody molecule.An antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen.
