we have examined usage of variable region gene families of the immunoglobulin heavy chain ( vh gene family ) in spleens of mrl/mpj-1pr/lpr ( mrl/lpr ) , ( nzb x nzw ) f1 , and bxsb mice by northern analysis using various vh probes , including the vhpar gene which we cloned and identified as a gene encoding the heavy-chain variable region of antipoly ( adp-ribose ) antibody .
