Transferrin Antigen ≥95%

Purified human transferrin antigen is supplied as a lyophilized powder by Antibodies.com, formulated for use as an immunogen, calibration standard, or capture reagent in immunoassay development. Each vial contains 300 mg of ≥95% pure transferrin with ≥1100 µg iron per gram of protein, reflecting physiological iron saturation that supports reproducible behavior in ELISA, western blot, and immunohistochemistry workflows. Reconstitute in an appropriate aqueous buffer immediately before use, and store the lyophilized powder refrigerated and protected from light to preserve antigenicity. Intended for in vitro research use only, this well-characterized antigen supports antibody validation, epitope mapping, and assay standardization studies where defined transferrin binding activity is required.
