Used in reproductive biology research to accurately measure levels of rat chorionic gonadotropin beta subunit in biological samples such as serum or plasma. This ELISA kit enables scientists to study placental function and fetal development in rat models, particularly during pregnancy. It is widely applied in endocrinology and toxicology studies to assess hormonal changes, monitor gestational health, and evaluate the impact of drugs or environmental factors on reproductive systems. Due to its high sensitivity and specificity, it supports reliable quantification essential for experimental consistency and data accuracy in preclinical research.
