小鼠 IL-12蛋白|IL-12 protein|IL-12(Mouse, C-His)（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 a polyhistidine tag 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 a polyhistidine tag 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：> 90 % as determined by SDS-PAGE
蛋白活性：1. Measured by its ability to bind biotinylated recombinant mouse IL12RB2 in a functional ELISA. 2. Measured in a cell proliferation assay using Anti-CD3-stimulated PBMC. The ED50 for this effect is typically 2-8 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, comprises 528 (204 + 324) amino acids and has a calculated molecular mass of 60.3 (23.1 + 37.2) kDa. The apparent molecular mass of rh IL12 heterodimer is approximately 28 & 47 kDa respectively in SDS-PAGE under reducing conditions.
