Used in research settings to measure levels of 17β-estradiol in biological samples from bovine sources. This ELISA kit enables accurate quantification of estradiol concentrations in serum, plasma, milk, or tissue extracts, supporting studies in reproductive physiology, endocrinology, and fertility monitoring in cattle. It is particularly useful for assessing hormonal changes during estrous cycles, pregnancy, or in response to treatments. The assay offers high sensitivity and specificity, allowing researchers to conduct large-scale screening with reliable results. Not intended for diagnostic or therapeutic use.
