Collagen beads and tissue culture

[Vincent J Magrini]

Hello group!!!!

	I have a question to any who is concerned.  Actually, I would 
like to increase the number of vero cells in tissue culture flasks (75 
cm^2) using collagen beads, but have never done so.... Has anyone used 
the collagen beads to increase cell concentrations?  If so, how much 
greater is the yield?  Yes, I could probably order larger flasks but must 
use what I have.  The purpose is to increase yields of enteric viruses 
which max at 10^5 viruses/cell.  Any and all insight is welcome.  Thanks.

Sincerely, 

Vincent J. Magrini
