Human Kappa (κ) and Lambda (λ) Free Light Chain Assays

Kappa Free Light Chain (FLC) is a 22kD protein while Lambda FLC is usually a dimer of 44kD as presented in the serum. Elevated levels of Kappa or Lambda FLC are associated with plasma cell disorders such as multiple myeloma, lymphocytic neoplasms, Waldenström’s macroglobulinemia, AL amyloidosis, light chain deposition disease and connective tissue diseases such as systemic lupus erythematosus.
