| Add. information | The units are determined by use of a Human IFN Alpha A (Hu-IFN-αA [2a]) laboratory standard calibrated to the international reference standard for Human Interferon Alpha A (Hu-IFN-αA [2a]) provided by the National Institutes of Health [Meager, et al. (2001) J. Immunol. Methods. 257(1-2):17-33]. On L929 cells the laboratory standard has been calibrated to the reference standard for Mouse Interferon Alpha provided by the National Institutes of Health. Lot Activity was derived from multiple determinations in the above assay. Please note that IFN assays vary between labs and assay systems [Meager, et al (2001). J. Immunol. Meth. 257:17. Meager and Das (2005) J. Immunol. Meth. 306:1]. |
