Use of α1G subunit of T-type calcium channel as diagnostic marker for pregnancy in cattle

摘要

The present invention relates to a marker composition for pregnancy diagnosis in cattle, a pregnancy diagnosis composition, and a pregnancy diagnosis method, which use a pregnancy-specific protein in cattle. The present inventors discovered an α1G subunit protein of the T-type calcium channel expressed specifically in pregnant cows, and produced a specific antibody against this protein. Therefore, the present invention has the effect of detecting pregnancy in cows easily, quickly, and accurately early in the pregnancy.
