Monoclonal Antibody to Blood Group Glycosyltransferases, Produced by Hybrids Constructed with Epstein-Barr-Virus-Transformed B Lymphocytes from a Patient with ABO-Incompatible Bone Marrow Transplant and Mouse Myeloma Cells

Abstract
A patient with chronic myeloid leukemia secreted an antibody to blood group glycosyltransferases after ABO-incompatible bone marrow transplatation (B recipient/O donor). Peripheral B lymphocytes from the recipient were transformed with Epstein-Barr virus, and then fused by polyethylene glycol with mouse myeloma cell line P3-X63/Ag8.653. After the cloning of the hybridoma cells, a cell line which produced human IgM antibody to blood group glycosyltransferases was established. The antibody completely neutralized B transferase activity at low concentration, while a larger amount of immunoglobulins was required to neutralize A transfer activity.
