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.
The immunoglobulin heavy chain (IgH) is the large polypeptide subunit of an antibody (immunoglobulin). In human genome, the IgH gene loci are on chromosome 14. A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains. Several different types of heavy chain exist that define the class or isotype of an ...
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 ...
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.
Each anti-immunoglobulin solution is artificially colored to ensure that the solution matches the color map at top. Immunofixation electrophoresis, schematic representation: - A. Normal serum - B. Monoclonal intact immunoglobulin IgGλ - C, D. Monoclonal intact immunoglobulin IgDλ and free light chain λ (Fλ).
An antibody molecule. The two heavy chains are colored red, blue, and purple. The two light chains green and yellow. See also: The immunoglobulin light chain is the small polypeptide subunit of an antibody (immunoglobulin). A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains.
It is important in quantification of free light chains in diseases such as multiple myeloma. Quantification is important for disease classification and for disease monitoring once a patient has been treated (increased skewing of the ratio between kappa and lambda light chains after a patient has been treated is an indication of disease recurrence).
