Long Ranger

[brito at WUSTLB.WUSTL.EDU]

Hy there,

This might have already appeared in the net but I'll ask anyway. Does anyone
out there know why the Long Ranger works like a wedged gel? I think is 
something related to the cross-linker (using something other than Bis-acryl.),
but I'm not sure.
As they are really expensive ($ 200 for 500 ml bottle!!) I wanted to know
whether it would be easy to make my own...

Thanks a lot,
