These unlinked chains are … The production of free immunoglobulin light chains in normal individuals is approximately 500 mg/day from bone marrow and lymph node cells. There is approximately 40% excess immunoglobulin light-chain production over immunoglobulin heavy-chain synthesis. Possibly this is simply to allow proper conformation of the intact immunoglobulin molecules, but an immunological role for the free light chains has also been proposed. There are approximately twi… cf1472d
