Used to measure the activity of Arylalkylamine N-acetyltransferase (AANAT) in mouse samples, this ELISA kit is essential in research related to melatonin synthesis and circadian rhythm regulation. It enables quantification of AANAT levels in pineal gland tissues or cell lysates, supporting studies on sleep disorders, hormonal regulation, and neuroendocrine function. The assay is widely applied in preclinical research, particularly in neuroscience and chronobiology, allowing researchers to assess how genetic, environmental, or pharmacological factors influence AANAT expression and activity in mouse models.
