Re: Mixed Waste

["Patrick D. Beyer" <pbeyer@post.its.mcw.edu>]

The material is cells that have been homogonized and processed to check 
on conductance of synaptosomal potassium. The tissues are from brains in 
the MCW Alzheimers Desiese Brain Bank. All the nuclides used are strickly 
from research activities, none are from in-vivo studies. I will have to 
check on the state regs because that is pretty much the issue. We aren't 
licensed for infectious waste, but i assumed that they are following the 
CDC Guidlines, perhaps not.......
