High Density (HD) SNP chip for Sheep

August 2012

The International Sheep Genomics Consortium (ISGC) is currently developing a next generation SNP chip capable of genotyping up to 700 thousand loci for the sheep research community. During 2012, the consortium has completed whole genome sequencing and variant detection using 75 individuals drawn from 41 breeds and wild sheep. The group is currently working to complete SNP filtering and chip design, and details about the project and its participants are available here.

The ISGC is pleased to announce that Illumina has been selected as the manufacturer and commercializer. This extends the close working partnership between the ISGC and Illumina that underpinned the development and release of the ovine SNP50 BeadChip.

Researchers who may be interested to purchase the new ovine HD BeadChip are now asked to register. This can be completed by making e-mail contact with Karl Sluis (ksluis@illumina.com), Cindy Lawley (clawley@illumina.com) and John McEwan (john.mcewan@agresearch.co.nz). For those researchers who registered an interest earlier in the year, we ask that you do so again. Key points and dates associated with the process are listed below:


  • 1. The consortium is aiming to complete the design phase within the next 4 - 6 weeks.
  • 2. The current time-line will see the first batch of HD SNP BeadChips shipped before December 31st 2012.
  • 3. The reagent cost has been set at $US152 / sample for the first 12 months.
  • 4. To receive this consortium pricing, purchase orders need to be signed in September 2012, even for BeadChips scheduled for delivery well into 2013.


For further enquiries about obtaining BeadChips or the design specifics of the array, please contact Karl Sluis, Cindy Lawley, John McEwan or James Kijas (James.Kijas@csiro.au). On behalf of the ISGC
