Bence Jones protein is a monoclonal globulin protein or immunoglobulin light chain found in the urine, with a molecular weight of 22–24 kDa. [1] Detection of Bence Jones protein may be suggestive of multiple myeloma or Waldenström's macroglobulinemia. [citation needed]

WebMore lambda than kappa light chain proteins make up the amyloid in these cases, and it appears that lambda-chains are more prone to fibril formation than kappa-chains. Immunoglobulins are thus the precursor protein for AL amyloid, which shows that primary amyloidosis belongs to the plasma cell dyscrasias. WebIn AL amyloidosis, lambda light chains are more common than kappa light chains by approximately 3:1 . All seven patients with available FLC data had an abnormal FLC ratio and dFLC level. Therefore, if a patient has neuropathy and a high dFLC level, AL amyloidosis should be considered as a diagnosis and a nerve biopsy may help to … イタリアトスカーナ
