Recombinant Mouse TNF-alpha Protein种属: 小鼠(Mouse) Accession #: P06804表达系统: E. coli 蛋白标签: No tag 内毒素水平: <0.01 EU/μg生物活性: Measured in a cytotoxicity assay using L‑929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D (Catalog # A113142). The ED₅₀ for this effect is typically <0.1 ng/mL.
-
Recombinant Human TNFRSF1A Protein种属: 人(Human) Accession #: P19438表达系统: E. coli 蛋白标签: No tag 内毒素水平: <0.1 EU/μg生物活性: Fully biologically active when compared to standard. The ED₅₀ as determined by its ability to inhibit the TNF-alpha mediated cytotoxicity in the L-929 cells is less than 0.05 μg/ml in the presence of 0.25 ng/mL of rHuTNF-alpha.
-
Recombinant Human Leptin Protein种属: 人(Human) Accession #: P41159表达系统: E. coli 蛋白标签: No tag 内毒素水平: <1.0 EU/μg生物活性: Fully biologically active when compared to standard. The ED50 as determined by a chemotaxis bioassay using human Leptin R transfected BaF3 murine proB cells is less than 2 ng/ml, corresponding to a specific activity of > 5.0 × 105 IU/mg.
-
Recombinant Mouse G-CSF Protein种属: 小鼠(Mouse) Accession #: P09920表达系统: E. coli 蛋白标签: No tag 内毒素水平: <0.1 EU/μg生物活性: Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine NFS-60 cells is less than 0.05ng/ml, corresponding to a specific activity of >2.0 ×10⁷ IU/mg.
-
Recombinant Human Interferon alpha 1 Protein种属: 人(Human) Accession #: P01562表达系统: E. coli 蛋白标签: No tag 内毒素水平: <0.1 EU/μg生物活性: Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.0 × 108 IU/mg.
