Bence Jones Proteins

A myeloma protein, Du, (γ1)2 (λ)2, is shown to have an extra cysteine residue in the light chain. This light chain is from the same λ variable region subgroup as are two Bence-Jones proteins, X and Bau, which also have an extra cysteine residue. The position of this residue is the same in all three chains.
