CGSC Charges and Fees to For-Profit Organizations

Charges are on a Per-Strain Basis

The per-strain charge to for-profit companies, beginning March. 15, 2011 is $110/strain.

Exceptions are:
the special strain kits (e.g., Hfr kits and F-prime kits) of 16-19 strains, which will have a flat rate of $1300; the 5-strain gene-disruption set of Datsenko and Wanner, 2000 (PNAS 97:6640 ) $500; and very large sets, such as Singer-Gross Tn, CRIM, portions of the Keio collection,or other sets or subsets > 15 strains, which require discussion at the time of the request.

We do not want any of these charges to be prohibitive or in any way inhibit use of our strains; we are open to discussion about specific needs and constraints at any time. Contact the CGSC
