Used in biomedical research to quantify rat transferrin levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is essential for studying iron metabolism, anemia, and inflammatory responses in rodent models. It supports research in immunology, neuroscience, and toxicology by providing a reliable method to assess transferrin concentration, which reflects iron transport and blood-brain barrier integrity in experimental animals. Commonly applied in preclinical studies to evaluate disease progression and treatment effects.
