WebNov 9, 2024 · Normally, there is a slight excess of kappa and lambda light chains produced (free light chains). However, in diseases such as in multiple myeloma, the plasma cells may produce excessive or mutated light chains that do not associate with heavy chains. These abnormal free light chains can be detected with a free light chain test. WebWhile the molecular weight of both light chains is approximately 22.5 kilodaltons, in serum, κ free light chain (κ-FLC) exists primarily as a monomer and λ free light chain (λ-FLC) as a covalently-linked dimer with a molecular weight of approximately 45 kilodaltons.
