- 种属: 小鼠(Mouse)
- Accession #: P07750
- 表达系统: HEK293
- 蛋白标签: C-His
- 内毒素水平: <1.0 EU/μg
- 生物活性: Measured in a cell proliferation assay using assay using CTLL‑2 mouse cytotoxic T cells. The ED₅₀ for this effect is typically <1.8ng/mL.
-
Recombinant Human IL-4 Protein
- 种属: 人(Human)
- Accession #: P05112
- 表达系统: HEK293
- 蛋白标签: C-His
- 内毒素水平: <0.1 EU/μg
- 生物活性: Measured in a cell proliferation assay using TF 1 human erythroleukemic cells. The ED50 for this effect is 85-340 pg/mL, corresponding to a specific activity of 2.94 × 106~1.17× 107 units/mg.
-
Recombinant Human GDNF GMP Protein
- 种属: 人(Human)
- Accession #: P39905-1
- 表达系统: HEK293
- 蛋白标签: No tag
- 内毒素水平: <1.0 EU/μg
- 生物活性: Measured in a cell proliferation assay using SH‑SY5Y human neuroblastoma cells. The ED50 for this effect is 2-12 ng/mL in the presence of Recombinant Human GFRα‑1/GDNF Rα‑1 Fc Chimera. The specific activity of recombinant human GDNF is >5.0 x 10^5 units/mg, which is calibrated against the human GDNF Reference Standard (NIBSC code: 09/266). Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human GFRα‑1/GDNF Rα‑1 Fc Chimera at 1 µg/mL can bind Recombinant Human GDNF with an apparent Kd <1 nM.
-
Recombinant Human HGF GMP Protein
- 种属: 人(Human)
- Accession #: P14210-1
- 表达系统: HEK293
- 内毒素水平: <0.1 EU/μg
- 生物活性: Measured by its ability to induce IL-11 secretion by Saos‑2 human osteosarcoma cells. The ED50 for this effect is equal or less than 4.00 ng/mL. The specific activity of recombinant human HGF is >1.0 x 10^6 IU/mg, which is calibrated against the human HGF WHO International Standard (NIBSC code: 96/564).
