SAF-1 has been developed from the fin tissues of an adult gilt-head seabream (sparius aurata) without immortalising treatments. SAF-1 supports the replication of several common fish viruses such as lymphocystis disease virus (LDV), infectious haematopoietic necrosis virus (IHNV) and viral haemorrhagic septicaemia virus (VHSV). SAF-1 has a higher susceptibility to rhabdoviruses, especially UHNV. In the SAF-1 line, neither chromosome changes or differences from passage 50-70 have been detected, suggesting a normal karyotype and stable cell line.
