Human pre-B cells, which produce immunoglobulin heavy chain but do not produce immunoglobulin light chain, are shown to contain a 1-kilobase transcript homologous to immunoglobulin lambda light-chain genes. Detailed analysis of RNA and cDNA clones derived from these transcripts reveals that they originate from the distinct immunoglobulin lambda-like genes… CONTINUE READING
