Abstract
A method for judging a possibility of the onset of bovine leukemia caused by bovine leukemia virus BLV, wherein a bovine individual, in which an amino acid sequence defined by the amino acid numbers 75 to 78 of the β1 domain of the bovine MHC Class II DRβ chain is Val-Asp-Thr-Tyr, is judged to have a possibility of the onset of the leukemia; and a method for judging a resistance to the onset of bovine leukemia caused by the bovine leukemia virus BLV, wherein a bovine individual, in which an amino acid defined by the amino acid number 78 of the β1 domain of the bovine MHC Class II DRβ chain is Val, is judged to have a resistance to the onset of the leukemia.
Claims5
A method for judging a possibility of onset of bovine leukemia caused by bovine leukemia virus BLV, wherein a bovine individual, in which an amino acid sequence defined by amino acid numbers 75 to 78 of β1 domain of bovine MHC Class II DRβ chain is Val-Asp-Thr-Tyr, is judged to have a possibility of the onset of the bovine leukemia.
A method for judging a possibility of onset of bovine leukemia caused by bovine leukemia virus BLV, which comprises:
- (1) amplifying genome DNA isolated from a bovine individual by polymerase chain reaction (PCR) to prepare a PCR product containing a DNA coding for a part or full length of β1 domain of bovine MHC Class II DRβ chain, and
- (2) judging that the bovine individual, in which an amino acid sequence corresponding to amino acid numbers 75 to 78 of the β1 domain of the bovine MHC Class II DRβ chain is Val-Asp-Thr-Tyr in an amino acid sequence encoded by the DNA contained in the PCR product, has a possibility of onset of the bovine leukemia.
