RE: Active enzyme centrifugation

Juan Pablo,

I assume you mean the Type 1 "direct transfer" band-forming
centerpieces. These are indeed available in charcoal epon from
Beckman, part # 331359. I priced them recently and they are $1000 in
the US.

Subject: Active enzyme centrifugation


Dear RASMBers:

I am interested in doing some experiments of "active enzyme
centrifugation" in the analytical centrifuge (an Optima XL-A), but I
haven't found the centerpiece in any catalogue.  I searched the
Ultracentrifuge Beckman page but the search was unsuccessful.  I am
writing  to see if someone can give this information to get this
centerpiece.  Thank you for your help.

Best wishes to all.

Juan Pablo
