Multiplex screening for functionally rearranged immunoglobulin variable regions reveals expression of hybridoma-specific aberrant V-genes.
Modification of antibody effector functions is commonly performed by chimerization or humanization. Cloning of antibody variable regions from hybridomas represents a first step that is frequently hampered by the expression of non-functionally rearranged variable regions in hybridoma cells that originate from MOPC21-derived fusion partners. We now present a simple method to clone functionally rearranged V-genes, based on V-gene-specific multiplex PCR screening. Using this method we document the expression of aberrant V-genes that originate from the original B-cell used for the hybridoma generation, not from the fusion partner, and are - thus - hybridoma specific.
