The ED50 for this effect is 17 pg\/ml.","rong_jie_fang_fa":"Always centrifuge tubes before opening.Do not mix by vortex or pipetting.\nIt is not recommended to reconstitute to a concentration less than 100μg\/ml.\nDissolve the lyophilized protein in distilled water.\nPlease aliquot the reconstituted solution to minimize freeze-thaw cycles. ","chu_cun_fang_fa":"Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.\nReconstituted protein solution can be stored at 4-7°C for 2-7 days.\nAliquots of reconstituted samples are stable at < -20°C for 3 months.","yun_shu_tiao_jian":"The product is shipped at ambient temperature.\nUpon receipt, store it immediately at the temperature listed below.","bei_jing_shuo_ming":"IFNγ is the major interferon produced by mitogenically or antigenically stimulated lymphocytes. It is structurally different from type I interferon and its major activity is immunoregulation. It has been implicated in the expression of class II histocompatibility antigens in cells that do not normally produce them, leading to autoimmune disease. Interferon gamma is produced mainly byT-cells and natural killer cells activated by antigens, mitogens, or alloantigens. It is produced by lymphocytes expressing the surface antigens CD4 and CD8. IFNγ synthesis is induced by IL-2, FGF-basic, and EGF."}
