Used in research settings to quantitatively measure alpha-fetoprotein (AFP) levels in rat biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is particularly useful in studies related to liver function, hepatocellular carcinoma, and fetal development in rat models. It enables researchers to assess disease progression, evaluate therapeutic interventions, and investigate reproductive toxicology or developmental abnormalities. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of AFP in small sample volumes. Commonly applied in academic research, pharmaceutical development, and biomedical laboratories focusing on oncology, endocrinology, and prenatal health studies in rodents.
