Purification and properties of biologically active messenger RNA for a myeloma light chain.
A cell-free system derived from Krebs II ascites tumor has been used to assay biologically active mRNA for myeloma (MOPC-41) light chain during its purification by oligothymidylate-cellulose chromatography and sucrose gradient centrifugation. The purified mRNA directs the synthesis of a product that yields tryptic peptides corresponding to those derived from authentic myeloma protein and that f...
متن کاملAn Immunoglobulin Light Chain
Identification of the immunogens responsible for the production of pathogenic autoantibodies is a major problem in the field of autoimmunity. In the principal diseases that are thought to involve autoimmunization, rheumatoid arthritis, type I diabetes, and multiple sclerosis are examples, the instigating stimulus is unknown. Another example of the gap in our knowledge of disease-causing immunog...
متن کاملAtypical immunoglobulin light chain amyloidosis
BACKGROUND Primary immunoglobulin light chain amyloidosis (AL amyloidosis) is a plasma cell disorder which mainly affects heart, kidneys, liver, and peripheral nervous system. Cases of atypical AL amyloidosis presented as spontaneous vertebral compression fractures have been rarely reported, and data about the management and clinical outcomes of the patients are scarce. METHODS Herein, we pre...
متن کاملFunctional Immunoglobulin Light Chain Genes
Rearrangement of Ig genes proceeds during B cell differentiation in an orderly fashion. First the heavy (H) chain gene is rearranged in pre-B cells . These cells can express cytoplasmic A chain but no light (L) chain (1). The K light chain genes rear range next and if they fail to produce a functional gene on either chromosome the X light chain genes are rearranged (2) . It is generally believe...
متن کاملRecombinant DNA clones constructed from immunoglobulin kappa light chain messenger RNA.
Recombinant DNA clones have been generated from mouse myeloma MOPC 21 immunoglobulin kappa light chain mRNA. Complementary DNA (cDNA) synthesized on kappa light chain mRNA by reverse transcriptase was made double stranded and inserted into the bacterial plasmid vector, pMB9. Approximately 70 tetracycline-resistant transformed colonies containing kappa light chain mRNA sequences were identified ...
