Used for the quantitative analysis of Estriol (E3) levels in chicken biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to monitor reproductive health, assess fetal development, and study hormonal changes during pregnancy in poultry. It is a valuable tool in veterinary research, animal endocrinology, and breeding studies where precise measurement of estrogenic hormones is required. The assay provides high sensitivity and specificity, allowing for accurate detection of low concentrations of Estriol, which is critical in understanding hormonal dynamics in avian species.
