Strange. I worked wit h SF21 cells, and it was no problem there. And
they are derived from Sf9, as far as I know.

Try to digest the cells for 5 minutes with trypsin. Remove the trypsin
afterwards and try again to tap them of. Should work now.
For how long did you culture your cells before you got this viability?
Maybe another medium works better, we tried Grace's and TC100 and
TC100 worked better.
