Cell line:
DSMZ no.:
ACC 635
human (Homo sapiens)
Cell type:
embryonal kidney
highly transfectable derivative of the human primary embryonal kidney cell line 293 (ACC 305) carrying a plasmid containing the temperature sensitive mutant of SV-40 large T-antigen (tsA1609neo); cells originally referred to as 293tsA1609neo; cells were described in the literature to be Geniticin (Neomycin, G418) resistant and to express SV-40 large T at 33°C, but not at 40°C; classified as risk group 1 according to the German Central Commission for Biological Safety (ZKBS)
14893, 14495, 14839
Biosafety level:
1, GMO-S1
Risk assessment:
The cell line was established by transfection of the cells with sheared DNA of adenovirus type 5. The cells contain 4 to 5 copies of the left end of the virus (12% of the viral genome) including E1a and E1b genes and one copy of the right end of the virus (10% of the genome) including the E4 gene. No active viruses are produced.
Permissions and restrictions:
