Functional scFv antibody sequences against the organophosphorus pesticide chlorpyrifos.

摘要

Two functional single-chain Fv (scFv) antibodies that recognize specifically the widely used organophosphorus pesticide chlorpyrifos-ethyl were derived from two murine hybridoma cell lines. It is shown that the functional scFvs could be isolated without any rounds of selection, with a success rate dependent on the efficiency of amplification of the functional light chain gene family by the specific primers. Besides four new functional immunoglobulin variable gene sequences, the isolation of a new pseudogene is reported.
