Used in research settings to measure norepinephrine levels in chicken biological samples such as plasma, serum, or tissue homogenates. This ELISA kit enables scientists to study stress responses, neuroendocrine activity, and autonomic nervous system function in poultry. It is particularly useful in agricultural and veterinary research to evaluate the impact of environmental stressors, diet, disease, or management practices on chicken welfare and productivity. The assay provides a sensitive and specific quantitative analysis, supporting studies in animal physiology, pharmacology, and behavioral science.
