Can Sf9 cells in Sf-900 III SFM (Cat. No. 12659017) be thawed and grown in Sf-900 II SFM instead?

It should be okay to thaw the cells into Sf-900 II SFM. This is a richer media compared to the Sf-900 III SFM so the cells would have an easy time adapting. We would recommend taking the cells through 3 passages in the new medium before using them for any experiments as that they have enough time to adapt.

What antimicrobials can be used in insect culture and at what concentration?

Many antibiotics are suitable for use with insect cells. The following antibiotics are commonly used:
- Penicillin/Streptomycine: 50-100 U/mL; 50-100 µg/mL
- Amphotericin B (Fungizone antimycotic): 0.25 µg/mL
- Gentamicin: 0.5 mL of 10 mg/mL solution in 500 mL media (final concentration: 10 µg/mL)

Is it necessary to heat-inactivate my serum before adding it to my medium?

Heat inactivation is not necessary. Our team has routinely used serum that has not been heat-inactivated, and we have not observed any effect on cell growth or morphology.

Many cells do not require heat-inactivated FBS. Some cells prefer heat-inactivated FBS. For instance, we use heat-inactivated FBS for our insect cell lines, i.e., Sf9 and Sf21 cells.
