title: A new mouse myeloma cell line that has lost immunoglobulin expression but permits the construction of antibody-secreting hybrid cell lines.
abstract: We have isolated a subclone of the mouse myeloma cell line P3-X63-Ag8 that does not express immunoglobulin heavy or light chains. This clone X63-Ag8.653 can be used for efficient fusion with antibody-forming cells to obtain hybrid cell lines producing pure monoclonal antibodies. Screening of hybrid cell lines for specificity and immunoglobulin classes was done with a modified enzyme-linked immunosorbent assay.
