Used in biomedical research to measure progesterone levels in non-human primate samples, particularly in studies related to reproductive physiology, pregnancy monitoring, and hormonal regulation. Enables researchers to quantify progesterone concentration in serum, plasma, or other biological fluids with high sensitivity and specificity. Commonly applied in fertility studies, ovarian function analysis, and evaluation of menstrual cycle dynamics in primate models. Supports endocrine research in pharmaceutical development, wildlife conservation, and comparative reproductive biology.
