Used to measure thyroid peroxidase (TPO) activity in rat samples, this ELISA kit is essential in thyroid function research and toxicology studies. It enables accurate quantification of TPO enzyme levels, which plays a key role in thyroid hormone synthesis. Researchers use it to evaluate thyroid disruption caused by drugs, environmental chemicals, or disease models in preclinical studies. The kit supports investigation into autoimmune thyroid disorders, endocrine disruption, and drug safety assessment in rodent models. Its high sensitivity and specificity make it suitable for detecting subtle changes in TPO activity in serum, plasma, or tissue homogenates.
