Abstract
The lambda-light-chain and lambda-heavy-chain variable-region genes of an anti-Rh(D) (Rh, Rhesus; D, heavy-chain diversity region) human monoclonal antibody secreted by lymphocytes transformed by the Epstein-Barr virus have been cloned and sequenced. Sequence comparison of the anti-Rh(D)mAb lambda-chain variable region with those of the other available human lambda chains revealed that it belonged to the human V lambda I (V lambda, variable region of lambda chain) subgroup. The greatest sequence similarity (80%) was observed with that of another anti-Rh antibody lambda-chain directed against the Rh(c) antigen. For the VH (VH, variable region of heavy chain) sequence, the highest similarity (86%) was observed with the germline VHG3 gene which belongs to the VHI subgroup. The expressed DH sequence of the anti-Rh(D) antibody is also of germline origin and complementarity-determining region 3 is thus produced by VH-DH and DH-JH (J, joining region) joining without recombination of multiple DH gene segments.
