We would like to purchase the positive control of this antibody. Could you please check if you have this product? https://www.abcam.com/index.html?pageconfig=datasheet&intAbID=23480 Thank you!

Answer

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.
