Objective To construct DNA double strand break(DSB) repair protein hKu70 deficient cell strain and to observe its biological characters for studying the functions of hKu 70 gene and the effects of occupational harmfulness factors on DSB repair.

Objective To construct the pEGFP\|C1\|K vector,an eukaryotic expression plasmid of DNA double\|strand break(DSB) repair gene hKu 70 antisense RNA and provide experimental material for the studies of hKu 70 gene function and toxicology.
