Development and characterization of polyclonal antibody against human kappa light chain in rabbit
Polyclonal antibodies against kappa light chain are used to diagnose diseases producing free light chain. The kappa and lambda light chains are products of immunoglobulin synthesis and released into the circulation in minor amounts such as serum, cerebrospinal fluid, urine and synovial fluid in normal condition. The purpose of this study was the production and purification of polyclonal immunog...
متن کاملFree immunoglobulin light chains in connective tissue diseases.
The basic immunoglobulin subunit consists of two heavy and two light chains held together by covalent disulphide bonds. In most cases of myeloma and Waldenstrom's disease there is an excess synthesis of light over heavy chains, resulting in Bence Jones proteinaemia and proteinuria. Furthermore, in some cases ("light chain disease"), there is absence of detectable heavy chain synthesis, and the ...
متن کامل[Clinical value of the blood measurement of the free light chains of immunoglobulins].
Monoclonal free light chains are found in the serum and urine of patients with B-cell proliferative disorders, including multiple myeloma. Measuring free light chains in serum is useful for the diagnosis and monitoring of free light chains diseases. Moreover it could be interesting in the monitoring of treated multiple myeloma with complete immunoglobulin and of monoclonal gammapathy of undeter...
متن کاملRadioimmunoassay of free light chains of immunoglobulins in urine.
We describe radioimmunoassays for kappa and lambda light chains of immunoglobulins in urine. The assays, which involve antisera to free light chains, were sufficiently sensitive to measure the light chains in unconcentrated urine from healthy subjects. The usefulness of the assays in clinical practice is illustrated by measurements of light chain excretion by patients, including serial studies ...
متن کاملBiochemical and aggregation analysis of Bence Jones proteins from different light chain diseases
Deposition of immunoglobulin light chains is a result of clonal proliferation of monoclonal plasma cells that secrete free immunoglobulin light chains, also called Bence Jones proteins (BJP). These BJP are present in circulation in large amounts and excreted in urine in various light chain diseases such as light chain amyloidosis (AL), light chain deposition disease (LCDD) and multiple myeloma ...
