Used for the quantitative determination of estradiol (E2) levels in sheep biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is specifically designed for research purposes in reproductive physiology studies, enabling accurate monitoring of estradiol fluctuations during the estrous cycle, pregnancy, or in response to hormonal treatments. It supports investigations into fertility, ovarian function, and endocrine disorders in sheep, providing a reliable tool for animal science and veterinary research. The assay is sensitive, reproducible, and suitable for high-throughput analysis in laboratory settings.
