with respect to immunoglobulin synthesis , two stable clones were selected by single cell cloning : clone lopra-1/5 synthesizes large amounts of alpha 2 heavy and kappa light chains , but secretes only small amounts of these molecules , whereas clone lopra-1/4 is clearly devoid of intracellular immunoglobulin heavy and light chains and thus appears to be a chain loss variant .
