Abstract

Single chain antibody fragment genes are commonly created by splicing together the immunoglobulin light chain (VL) and heavy chain variable (VH) genes of a monoclonal antibody produced by a hybridoma. Selective PCR amplification of the functional immunoglobulin variable gene rearrangements can be complicated by the existence of other unproductive immunoglobulin gene rearrangements in the hybridoma. Here we report the detection and preferential amplification of aberrant transcripts from two unproductive VH gene rearrangements derived from the fusion partner of a hybridoma. The functional VH gene of the monoclonal antibody was successfully amplified by selective use of primers to individual JH segments.
