IL-12 蛋白|IL-12 protein|IL-12(Mouse, Fc Tag)

小鼠 IL-12蛋白|IL-12 protein|IL-12(Mouse, C-human IgG1-Fc)（产品说明）
蛋白名称：IL-12蛋白, IL-12 protein
蛋白构建：A DNA sequence encoding the p35 subunit of mouse IL12, termed as IL12A (P43431) (Met 1-Ala 215) was fused with the Fc region of human IgG1 at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the p40 subunit of mouse IL12, termed as IL12B (P43432) (Met 1-Ser 335) was fused with the Fc region of human IgG1 at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified.
表达宿主：HEK293 Cells
蛋白纯度：> 85 % as determined by SDS-PAGE
蛋白活性：1. Immobilized mouse mIL12A+mIL12B at 10 μg/ml (100 μl/well) can bind biotinylated human IL12RB1-His (Cat:11674-H08H), The EC50 of biotinylated human IL12RB1-His (Cat:11674-H08H) is 38.7-90.3 ng/ml. 2. Measured in a cell proliferation assay using Anti-CD3-stimulated PBMC. The ED50 for this effect is typically 0.2-0.8 ng/mL.
蛋白内毒素：< 1.0 EU per μg of the protein as determined by the LAL method
预测N端：Arg 23 & Met 23
蛋白分子量：The recombinant mouse IL12 heterodimer of IL12A/IL12B, both was Fc chimera, comprises 988 (434 + 554) amino acids and has a calculated molecular mass of 111.5 (48.7 + 62.8) kDa. The apparent molecular mass of rh IL12 heterodimer is approximately 55 & 75 kDa respectively in SDS-PAGE under reducing conditions.
