Cell Line Name

Sf21 TiterHigh AC free

Cell Line Description

This cell line is a derivative of the Sf21 cell line which has been adapted to TiterHigh Sf Insect Medium (Sigma I5408). TiterHigh Sf Insect Medium is an animal component-free, protein-free formulation designed specifically for the Sf21 (Spodoptera frugiperda) insect cell line. The cell line Sf21 is derived from pupal ovarian tissue of spodoptera frugiperda. The Sf21 cell line is highly susceptible to Baculovirus infection and is used in the production of protein products genetically manipulated into Baculovirus vector systems.

Culture Conditions

Subculture Routine

Maintain cultures between 3x100,000 to 1x1,000,000 cells/ml; 27°C. Gently resuspend cells in old culture medium by dislodging the cells by pipetting, or gentle agitation, and resuspend in fresh medium. Cells should stick to the culture flask. Freeze in 7.5%DMSO/92.5% 1:1 conditioned media:fresh media. Cultures may take up to 10 days to recover normal growth characteristics following cryopreservation and resuscitation.

Unless specified otherwise, at ECACC we routinely handle all of our cell lines at containment level 2 in accordance with the ACDP guidelines (Advisory Committee on Dangerous Pathogens) (UK). All cell cultures have the potential to carry as yet unidentified adventitious agents. It is the responsibility of the end user to ensure that their facilities comply with biosafety regulations for their own country.

The Culture Collections represent deposits of cultures from world-wide sources. While every effort is made to ensure details distributed by Culture Collections are accurate, 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 Culture Collections does not guarantee the passage number stated will be the passage number received by the customer.

Cultures supplied by 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.
