Used in reproductive biology research to accurately measure luteinizing hormone levels in rat serum or plasma samples. Enables study of hormonal regulation in the hypothalamic-pituitary-gonadal axis, particularly in experiments related to ovulation, steroidogenesis, and fertility. Widely applied in endocrinology studies, toxicology assessments, and drug development where monitoring LH fluctuations is critical. The kit supports high-throughput screening and provides reliable quantification, making it essential for longitudinal studies in rodent models.
