Coated plates for fluorescence imaging of baculovirus-infectedinsect cells?

Methods:

Which coating is best to keep baculovirus-infected insect cells adhered to microscope plates: poly-lysine, integrin, laminin, etc? Any recommendationson plate type and vendor availability?

I have a major problem doing FRET microscopy on Sf21 insect cells infected with recombinant AcNPV baculoviruses: following infection, the Sf21 cells detach from the glass microscope plate and roll around, especially when I change filter cubes (donor, acceptor, FRET dichroics) during photobleaching experiments.

I am expressing ER membrane proteins tagged with cyan and yellow fluorescent proteins (CFP, YFP).

Thanks,

No experience with Sf21 cells in terms of trying to keep them attached but
in all difficult cases CellTak (available from BD Bioscience) was far superior
to everything you list. You can coat yourself - involves adding solution, waiting
and rinsing.
