Thanks to those that replied to my query. Nearly half of the responses were from those keen to learn of any helpful replies. Here are the 6 responses that indicated a facility that would undertake microsatellite library development. 1. I've been using the GIS company (http://www.genetic-id-services.com/index.htm) to develop libraries of microsatellites in 2 bat species and was very happy with the results. This company also developpped microsats for many species of insects (http://www.genetic-id-services.com/species.htm) so it might interest you. All the best, Sebastien. 2. Ecogenics are not cheap, but they have always delivered what was requested: http://www.ecogenics.ch/ Best, Christoph 3. I am a graduate student in the Richard Stouthamer lab at the University of California, Riverside. We outsourced microsat. development to a company called GIS in Chatsworth, California. They are good quality primers and come with a potential library of over 100 markers. I worked with microsats (for a fish) from this company before and mapped close to 130 markers on the genome. If you have the money ($10000 US); it might be worth it. Good luck, James 4. We can develop the markers for you if you want here at the GT Genome Center. Let me know if you are interested.

Regarding your inquiry on Evoldir, I have very recently approached a Swiss company to get a quotation for developing a microsatellite library for some hoverflies. I'm attaching (reattached) their generalized pricelist FYI, which includes different options depending on how far you would like them to go with primer development and tests of polymorphism. I cannot give you any advise on the quality of their service since I haven't yet decided whether to use them. I would be interested in any other options, so if you don't mind forwarding other replies to me after collating them I would be very grateful! Best wishes, Luc 6. I had Ecogenics in Switzerland develop microsatellites for the comma butterfly Polygonia c-album. Butterflies are tricky, but they did it without problem. And for much less than it would have cost me to hire someone to (try) to do it! Cheers Soren Thanks again to all that replied.
