General Cell Collection: Sf21
|Cell Line Name:||Sf21|
|Keywords:||Spodoptera frugiperda pupal ovarian tissue|
|Cell Line Description:||Derived from pupal ovarian tissue of spodoptera frugiperda. The cells are highly susceptible to Baculovirus infection and are used in the production of protein products genetically manipulated into Baculovirus vector systems. They were derived at the USDA Insect Pathology Laboratory from a cell line originating from pupal ovarian tissue of the fall army worm, Spodoptera frugiperda. Sf21 cells have greater range in size and have a doubling time of 24 hr compared to 48-72 hr for Sf9 cells.|
|Subculture Routine:||Split sub-confluent cultures (70-80%) 1:2 i.e. seeding at 5x10,000 cells/cm²; 28 C. Gently resuspend cells in old culture medium by dislodging the cells by pipetting, or gentle agitation, centrifuge suspension and resuspend cell pellet in fresh medium. This is an adherent cell line but will grow successfully in suspension. Freeze in 10% DMSO/90% foetal bovine serum (FBS). Cultures may take up to 10 days to recover normal growth characteristics following cryopreservation and resuscitation.|
|Culture Medium:||SF90011 + 10% Foetal Bovine Serum (FBS)|

The HPA Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by HPA Culture Collections are accurate, HPA Culture Collections cannot be held responsible for any inaccuracies in the data supplied. References where quoted are mainly attributed to the establishment of the cell culture and not for any specific property of the cell line, therefore further references should be obtained regarding cell culture characteristics. Passage numbers where given act only as a guide and HPA Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.
Cultures supplied by HPA Culture Collections are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line.
