title: Variable-region sequences of five human lambda-chain proteins reacting with an idiotypic antibody to the MCG Bence-Jones protein.
abstract: An antibody to the V-region of BJ protein MCG has been used to detect other human lambda-chains with similar idiotypic specificities. Five such proteins have been found and sequenced. They show relatively strong sequence homologies to some segments of the MCG V-region. The results of this study indicate that L-chains which contain short segments of their V-regions that are identical can be readily detected by the use of appropriate antisera.
