Studying cartilage in SEM

Hi Paul --

I'm so glad you wrote!  -- I meant to get back to you much sooner, but 
had lost your contact info.

Not that I really want to turn customers away, but I was wondering if 
you had considered using the Beckman Cell Sciences Imaging Facility  
instead (  Although we do have a critical 
point dryer and SEM that would suffice for your needs, we really are 
designed to be a fabrication lab, not an analytical lab.  We completely 
lack the expertise to help you with your samples -- we could train you 
on the tools, but then sample prep (which is, as you probably know, 98% 
of the success in SEMming a biological sample) would be completely up to 
you.  And, you would be sharing with people making devices, so the 
systems are really not set up for biological analysis.  Beckman has a 
critical point dryer and SEM -- and most importantly, experts who know 
how to prep and image your samples.

If there is a reason that you would rather not use the Beckman center, I 
would really like to know, as we generally refer people with biological 
samples there.
