What is meant by light chain antibody?

What is meant by light chain antibody?

Light chains are proteins made by plasma cells, a type of white blood cell. Plasma cells also make immunoglobulins (antibodies). Immunoglobulins help protect the body against illness and infections. Immunoglobulins are formed when light chains link up with heavy chains, another type of protein.

How many light chains does an antibody have?

two light chains
Structure. 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 (CL) domain.

What does high free kappa and lambda light chains mean?

Kappa Free Light Chain Test. A kappa free light chain test is a blood test that checks for high levels of certain proteins in your blood. Elevated free light chains might mean you have a plasma cell disorder.

What are kappa light chain antibodies?

Antibodies that detect Kappa Light Chain can be used in several scientific applications, including Immunohistochemistry (Paraffin), Flow Cytometry, Immunocytochemistry, Peptide array and ELISA. These antibodies target Kappa Light Chain in Human, Mouse and Rat samples.

What is the immunoglobulin light chain?

The immunoglobulin light chain is the smaller subunit of an antibody and in humans can be expressed in two types: as a kappa ( kappa ) or a lambda ( lambda ) chain. Antibodies are produced by B-Cells that are clonal and each expresses only one type of light chain.

How are antibodies purified by peptide affinity chromatography?

Antibodies are purified by protein A and peptide affinity chromatography. Myosin is composed of six polypeptide chains: two identical heavy chains and two pairs of light chains. Myosin light chain 2 (MLC2), also known as myosin regulatory light chain (MRLC), RLC, or LC20, has many isoforms depending on its distribution.

How many types of light chain antibodies are there?

Kappa Light Chain Antibodies. Immunoglobulin classes share the same basic four polypeptide chain structure of two heavy chains (five types) and two light chains (kappa, lambda; both having a molecular weight of 22.5 kDa).
