Used in reproductive biology research to accurately measure follicle stimulating hormone levels in rat samples. Enables study of hormonal regulation in the hypothalamic-pituitary-gonadal axis. Commonly applied in experiments assessing fertility, ovarian and testicular function, and endocrine disruptions. Supports evaluation of drug effects, environmental toxin impacts, and genetic modifications on reproductive health in rodent models. Provides high sensitivity and specificity for quantitative analysis in serum, plasma, or cell culture samples.
