Used for the quantitative analysis of estradiol (E2) levels in chicken serum, plasma, or other biological samples. This ELISA research kit enables researchers to study reproductive health, monitor hormonal changes during the egg-laying cycle, and assess the effects of environmental or dietary factors on endocrine function in poultry. It is a valuable tool in veterinary research, animal physiology studies, and breeding program optimization. The assay provides high sensitivity and specificity, allowing accurate measurement of low-concentration hormones critical for endocrine disruption studies and reproductive performance evaluation.
