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 ...
Free light chains (FLCs) are immunoglobulin light chains that are found in the serum (blood) in an unbound (free) state. In recent decades, measuring the amount of free light chains (FLCs) in the blood has become a practical clinical test. FLC tests can be used to diagnose and monitor diseases like multiple myeloma and amyloidosis.
Anti-Lambda Light Chain Type Description; Anti-Lambda Light Chain [N10/2] This is a recombinant monoclonal antibody to the Lambda light chain. It does not cross react with Kappa light chains. N10/2 most importantly recognizes pathologies such as leukemias, plasmacytomas, and non-Hodgkin's lymphomas. [22]
Immunoglobulin E (IgE) is a type of antibody (or immunoglobulin (Ig) "isoform") that has been found only in mammals. IgE is synthesised by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing four Ig-like constant domains (Cε1–Cε4). [1]
The variable regions are composed of 7 amino acid segments; three of which are hypervariable regions or CDR (yellow) and four of which are FR(shown in green for heavy chains and pink for light chains). In molecular biology, a framework region is a subdivision of the variable region (Fab) of the antibody.
Amyloid light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form of systemic amyloidosis. [1] The disease is caused when a person's antibody-producing cells do not function properly and produce abnormal protein fibers made of components of antibodies called light chains.
The kappa (κ) and lambda (λ) chains of the immunoglobulin light chain loci rearrange in a very similar way, except that the light chains lack a D segment. In other words, the first step of recombination for the light chains involves the joining of the V and J chains to give a VJ complex before the addition of the constant chain gene during ...
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.
