Used in research settings to quantify human transferrin levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables accurate measurement of transferrin for studies related to iron metabolism, anemia, inflammation, and nutritional status. It is widely applied in clinical research, diagnostic laboratories, and pharmaceutical development to assess iron transport and regulation in human physiology and disease conditions. The assay is sensitive, specific, and suitable for high-throughput analysis.
