Source for Transposons (i.e. Tn4351)

[Joel Bader]

Can someone tell me where I can get transposons commercially?
Specifically I'm looking for a source for Tn4351. It was first isolated
from Bacteriodes fragilis by N. B. Shoemaker, ,C. Getty, J.F. Gardner,
and A.A. Salyers (1986)and it has been used for mutagenesis work in the
Cytophaga. Please respond to my personal e-mail, jabader at mindspring.com.
Thanks in advance!
