Abstract: A transgenic pig clonal somatic cell line expressing protectin CD59 gene is provided to minimize complement activation by inhibiting cytotoxicity destruction in xenotransplantation, so that the cell line is useful for inhibition of hyperacute rejection occurred by xenotransplantation. A transgenic pig clonal somatic cell line expressing protectin CD59 gene(KCLRF-BP-00139) contains an expression cassette pcDNA-CD59(neo) encoding CD59 gene having the nucleotide sequence of SEQ ID NO:1. A method for manufacturing the transgenic pig clonal somatic cell line expressing protectin CD59 gene(KCLRF-BP-00139) comprises the steps of: (1) separating a somatic cell from the fetal pig by using primers of SEQ ID NOs:2 and 3; (2) preparing an expression vector containing a CD59 gene and transducing the expression vector into the somatic cell; and (3) selecting and culturing the transduced somatic cells. Further, the CD59 gene is SEQ ID NO:1.
