Used to measure 5-alpha reductase (5AR) enzyme activity in rat biological samples, this ELISA kit is essential in endocrinology and metabolic research. It enables researchers to quantify the conversion of testosterone to dihydrotestosterone (DHT) in tissues such as prostate, liver, and skin. Commonly applied in studies related to hormonal disorders, prostate health, and the effects of drugs or natural compounds on androgen metabolism. The kit supports high-throughput screening in preclinical studies, especially when evaluating potential inhibitors of 5AR for treating androgen-dependent conditions. Its sensitivity and specificity make it suitable for monitoring enzyme activity changes due to genetic, environmental, or pharmacological factors.
