We would like to purchase the positive control of this antibody. Could you please check if you have this product? Thank you!


Thank you for your enquiry. Further to correspondence with the source of this antibody I can tell you that normal human plasma should be suitable as a positive control. The concentration of Gc-globulin in human plasma is approximately 400 µg/ml (Masuda S, Okano T, Osawa K, Shinjo M, Suematsu T, Kobayashi T (1989) Concentrations of vitamin D-binding protein and vitamin D metabolites in plasma of patients with liver cirrosis. J Nutr Sci Vitaminol 35:225-34.). I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
