Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Gently resuspend cells in the spent culture medium by pipetting across the monolayer or by hitting the flask against the palm of your hand (the latter is only preferable when working with larger flasks).
Subcultivation Ratio: A subcultivation ratio of 1:5 or greater is recommended
Medium Renewal: Every 2 to 3 days
Growth Conditions: The recommended media are formulated for use without CO2. Omission of the yeastolate or lactalbumin hydrolysate will lead to poor performance by this line.

Sf9 was cloned by G. E. Smith and C. L. Cherry from the parent line, IPLB-SF 21 AE, which was derived from pupal ovarian tissue of the fall armyworm, Spodoptera frugiperda, by Vaughn, et al., in 1977.
