Dear methods-and-reagents at net.bio.net

does anybody know any companies that sell SRACTAN?
Sractan is a polysaccharide (arabinogalactan) derived from larch and used in
many applications:food, pharmaceutical, agricultural, cosmetic and bio-tech
products.
I use it in making discontinuous gradients suitable for separating red blood
cells of different density by centrifugation. I bought stractan from Champion
International Corporation in Tacoma (Washington) but that Company doesn't make
it anymore.

Can anyone help me?
