Xenopus tropicalis ChIP-chip tile path arrays

Chromatin immunoprecipitation combined with genome tile path microarrays (ChIP-chip) or deep sequencing (ChIP-seq) can be used to study genome-wide epigenetic profiles and the transcription factor binding repertoire in early embryos. Over the last couple of years we have designed and tested Xenopus tropicalis genome-tiling arrays, including a genome-wide 5-array set and a promoter array for ChIP-chip. These designs are now available for anyone to use, and can be purchased from Roche-NimbleGen (will be on their web site shortly, but until then the design files can be used for custom ordering).

I have some free trops for anyone in Canada with an approved animal facility. All are fat and healthy. If you pay the shipping costs they are yours.

There are about 20 female out-bred Nigerians, originally from Nasco and about 20 crystallin-GFP females.

13th International Xenopus Conference

September 12 - 16, 2010

Chateau Lake Louise, Alberta, Canada

Keynote Speaker: Nancy Papalopulu, University of Manchester

The Conference website ( ) is now live and registration is open.

The organizers of the 13th International Xenopus Conference invite you to register for the conference and submit your abstract. The conference will begin on Sunday afternoon, September 12th and will end lunchtime on Thursday September 16th. We have an excellent list of invited speakers, and will also be selecting some abstracts for oral presentations. We encourage as many students to attend as possible and will be awarding $250 travel awards to at least 100 students.

The conference is being held in Banff National Park in the Canadian Rockies at the Fairmont Lake Louise. The venue overlooks the lake and glacier and is surrounded by fantastic hikes. Special rates have been negotiated with the hotel for rooms and meals for the meeting plus for 3 days prior and following, should you wish to spend some additional vacation time at this amazing venue. Guests are welcome. White water rafting, heli-skiing, climbing and other options are available. A hostel is located 2 km down the road for those on a limited budget. Some free time for hiking will be available each afternoon and more adventurous options available on the last afternoon of the conference. Evenings will have full lectures by featured speakers followed by poster sessions.

To attend please visit the conference website at <> and follow the detailed instructions. All pricing is in Canadian dollars, though US dollars are widely accepted in Canada. Attendees need to 1. register, 2. submit an abstract and 3. arrange accommodations/meals. The cost for accommodations, which includes all meals, coffee breaks etc. runs from CN$217-$311 a night. Some discounted accommodations are available for graduate students. Registration is CN$100. Details on travel arrangements are also available on the web site. Shuttles from the airport to the venue are being negotiated and details will be posted soon.

The conference will showcase all of the latest cutting edge research in Xenopus, encompassing cell, developmental and neurobiology plus of course genomics and genetics. The organizers are working hard to make this the best and most comprehensive Xenopus conference to date, and we very much hope you can join us at Lake Louise in September!
