Gary (and anyone following this thread),
			Thanks. As far I can 
tell, introgen's beads top our at 15 µm. Well 
that might be ok, but I was hoping to find 25 µm 
(it is our average cell diameter). Sorry I didn't 
make that clear (or perhaps there is a product I 
missed on their web page amid all of the smaller 
beads?).

	As ever
