• Assembler:

 Celera Assembler and UMD Overlapper.

• Sequencing Center :

 Baylor College of Medicine. 

• Source of DNA used for sequencing:

The source of the BAC library DNA was Hereford bull L1 Domino 99375, registration number 41170496. Dr. Michael MacNeil's laboratory, USDA-ARS, Miles City, MT provided the blood. The DNA for the whole genome shotgun sequences was provided by Dr. Timothy Smith's laboratory, U.S. Meat Animal Research Center, Clay Center, NE from white blood cells from L1 Dominette 01449, American Hereford Association registration number 42190680 (a daughter of L1 Domino 99375). A skin cell fibroblast cell line from the same animal is available from Dr. Carol Chitko-McKown's laboratory, although there is no sequence from that cell line.
