Source for Oligo(dT)30 latex?

[Thomas Newman]

I am trying to locate a US source for Oligo(dT-30) latex for use in cDNA
subtraction.  Hara et al.  NAR 19: 7097-7104 (1991) gave Nippon Roche Co.,
Ltd., Japan Synthetic Rubber Co as a source, but I do not know how to
contact this company.  If anyone has their contact numbers, or preferably
knows of a US source, I would appreciate this information very much.

I already have oligo-dT on paramagnetic particles, but need the latex
material in addition.		

Thanks in advance,
