Objective: To investigate the function of POLH(polymerase eta) through establishment of the POLH gene-blocked cell line FL-POLH(-).
Methods: A mammalian expression vector expressing antisense POLH gene fragment pMAMneo-amp-POLHA (-) was constructed by cloning the 1473 - 2131 fragment of POLH gene into the mammalian expression vector pMAMneo-amp(-) in antisense orientation. The FL cells were transfected with this antisense RNA expressing vector and selected by G418.
