Heparin column, question to users

[Albert D.G. de Roos]

Hello, we are a small group in Nijmegen (Netherlands) working 
on bone morphogenetic proteins (BMPs).
At present we are trying to purify BMPs from culture supernatants,
for which we want to use a heparin column. My question is:
is there somebody close to Nijmegen who has such a column in the lab,
so that we could try whether such a purification method is useful
for us?

If so, please contact: boersma at sci.kun.nl
