The structure and size of selected protein binder scaffolds. The structures of different protein binder scaffolds are shown; variable regions are marked in brown. (A) Conventional human immunoglobulin (IgG) antibody, consisting of two heavy (blue) and two light (orange) chains connected by disulphi...
An antibody’s mode of action varies with different types of antigens. With its two-armed Y-shaped structure, the antibody can attack two antigens at the same time with each arm. If the antigen is a toxin produced by pathogenic bacteria that cause an infection like diphtheria or tetanus, ...
c. The antibody's antigenic determinants—called isotypes, allotypes, and idiotypes—determine the variability in an- tibody structure. 1) Isotypes are variants present in all members of a species. 2) Allotypes are variants caused by intraspecies genetic differences. 3) Idiotypes are variants ...
Figure 1. Schematic representation of the recepteur d’origine nantais (RON) structure and its variants. (a) Human RON comprises 20 exons encoding a 180-kDa protein with 1400 amino acids [4]. The classical promoter containing SP-1 and AP-2 binding elements is responsible for transcription of...
cation have been discussed.2 Nevertheless, the overall instability and stabilization of antibody drug candidates have not been carefully examined in the literature. This article, not meant to be exhaustive, intends to review the structure and functions of antibodies, discuss their instabilities, and ...
antibody structureThe four-chain structure of an antibody, or immunoglobulin, molecule. The basic unit is composed of two identical light (L) chains and two identical heavy (H) chains, which are held together by disulfide bonds to form a flexible Y shape. Each chain is composed of a variabl...
more likely to be found in the complementarity-determinig regions that in the framework of the variability of the residue in FVs (the modules containing variable domains of the light and heavy chains) of known three-dimensional structure indicates that tryosines and tryptophans are more exposed ...

the field of monoclonal antibody development represents a novel way in which to target specific mutations and defects in protein structure and expression in a wide range of diseases and conditions. Today, with major rapid advancements in genetic sequencing and the translation of basic medical sciences...
