To the Tetrahymena community,
Since 2006, the Tetrahymena Stock Center at Cornell has supplied T. thermophila strains to
> 60 different labs in 15 countries worldwide (for our current list of clients see Table 1 below). As
part of our effort to update the community on the activities of the Center, we are excited to share
with you the resources now available and ask for your feedback on additional services you would
like to see. Please send us any ideas, suggestions for additions, links, protocols, etc or give us a
call. We want to hear from you.
At present, more than 700 strains are available for order through the Center’s website
(http://tetrahymena.vet.cornell.edu/ ). The site provides information about strains as well as
mechanisms for placing orders and making deposits. The site currently includes the following:
• A downloadable pdf listing of all of the strains currently available through the Stock Center,
accessible at http://tetrahymena.vet.cornell.edu/strains.html. A brief tutorial on searching the
strain pdf can be found at http://tetrahymena.vet.cornell.edu/searching.html.
• A semi-automated ordering form that can be emailed directly to the Stock Center
(http://tetrahymena.vet.cornell.edu/extras/TetrahymenaOrderForm.pdf).
• A Strain deposition form for use with small numbers of strains
(http://tetrahymena.vet.cornell.edu/extras/TetrahymenaDonorForm.pdf ). For large scale
deposits, a downloadable Excel file with all of the required field variables already inserted can be
found at (http://tetrahymena.vet.cornell.edu/extras/DonorFieldNames.xls ). Instructions for filling
out the forms and a description of the information requested in each field is also provided. For
those desiring more help or information, please contact us. We want to work with you to facilitate
the easy transfer of critical strains you want saved at the Stock Center.
• A simple glossary of known mutants which is being expanded as new strains are added
(http://tetrahymena.vet.cornell.edu/glossary.html ). If you have mutant strains which are not
listed, please let us know. We want to add your strain to our collection and to our glossary.
• A photo gallery of Tetrahymena images sent to us by various labs (thank you to all who sent
us images!). Please take a look and send us your pictures for inclusion in the gallery
(http://tetrahymena.vet.cornell.edu/ ).
• A list of links to other Tetrahymena sites (http://tetrahymena.vet.cornell.edu/otherlinks.html
). Please send us any additional links you think should be included.
We are continuing to receive deposits from other laboratories and the number of strains
available through the resource is expected to increase dramatically over the next year. A
competitive renewal for continued funding for the Center through the National Institutes of Health
Center for Research Resources (NCRR) is currently under review. Our new proposal includes
support for maintenance and community annotation of the Tetrahymena Genome Database (TGD),
which we regard as essential to the community as a whole.
Clearly, continued funding for the Tetrahymena Stock Center requires your continued interest
and support. Please use the Stock Center whenever you need to obtain cells or want to make your
strains available to the community. To save your time, and to help establish the Tetrahymena
Stock Center as a centralized resource for obtaining Tetrahymena cell lines, please refer any
inquiries you receive about obtaining stocks to us (contact us). We also want to stress that the
Stock Center is now accepting deposition of strains from all laboratories. Contact us to discuss
your specific needs.
One final point – we are committed to supplying cells to all who need them, regardless of
ability to pay. However, the reality is that to survive we need to be able to shift at least some of
the cost of maintaining the Stock Center to users. We have kept our fees as low as possible.
Currently the Stock Center charges $30/strain, $150/mating panel, $10 FEDEX shipping in the
U.S. and “at cost” shipping outside the U.S. These costs will undoubtedly rise, especially in light of
the rapidly increasing cost of shipping. One simple way to insure that labs have the funds
necessary to obtain cells from the Stock Center is to include the costs of obtaining cells in funding
requests. Therefore, please include the cost of obtaining cells from the Stock Center in your grant
proposal budgets as a way to insure that you have access to strains deposited in the Tetrahymena
Stock Center.
