This may well be true, since Qiagen is the American offspring of
Diagen GmbH.  All my packages of Qiabrane nylon membrane are clearly
labelled "made in Germany".  I assume all their stuff is made in
Germany.  But why would the same manufacturer market the same
material through a competing US company?
