Only one type of light chain is present in a typical antibody, thus the two light chains of an individual antibody are identical. Each light chain is composed of two tandem immunoglobulin domains: one constant (C L) domain; one variable domain (V L) that is important for binding antigen; The approximate length of a light chain protein is from ...
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
The universal structure of antibody includes the constant regions part of the fragment crystallizable(Fc) region of the antibody (shown in dark blue). It also includes the fragment antigen binding which is composed of one heavy and one light chain (shown as L for light and H for heavy).
Antibody (or immunoglobulin) structure is made up of two heavy-chains and two light-chains.These chains are held together by disulfide bonds.The arrangement or processes that put together different parts of this antibody molecule play important role in antibody diversity and production of different subclasses or classes of antibodies.
The "upper" part of an antibody.The complementarity-determining regions of the heavy chain are shown in red (. Complementarity-determining regions (CDRs) are polypeptide segments of the variable chains in immunoglobulins (antibodies) and T cell receptors, generated by B-cells and T-cells respectively.
Schematic diagram of a typical antibody showing two Ig heavy chains (purple) joined by disulfide bonds to two Ig light chains (green). The constant (C) and variable (V) domains are shown. An antibody molecule. The two heavy chains are colored red and blue and the two light chains green and yellow. [1]
Colors are: H-chains (blue and light blue), L-chains (red and light red), J-chain (magenta) and the secretory component (yellow). Coordinates of each backbone carbon atom were derived PDB entry 3cm9. [2] Immunoglobulin A (Ig A, also referred to as sIgA in its secretory form) is an antibody that plays a role in the immune function of mucous ...
Anti-Kappa Light Chain Type Description; Anti-Kappa Light Chain [NH3/41.34] This is a recombinant monoclonal antibody to the kappa light chain. Specifically, [NH3/41.34] binds to IgG antibodies via Western blot. There is no cross reactivity with cynomolgus monkey IgG1 and cynomolgus monkey IgG4, which are recognized by Anti-IgG [NH3/130.5.2]. [23]
