Recombinant Human Parathyroid Hormone Protein
- 种属: 人(Human)
- Accession #: P01270
- 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 its ability to induce cAMP accumulation in murine MC3T3E1 cells is less than 50 ng/ml, corresponding to a specific activity of > 2.0 × 104 IU/mg.
-
Recombinant Human IL-18 Protein
- 种属: 人(Human)
- Accession #: Q14116
- 表达系统: E. coli
- 蛋白标签: No tag
- 内毒素水平: <10 EU/mg
- 生物活性: 1、Measured by its ability to induce IFN-gamma secretion by KG‑1 human acute myelogenous leukemia cells in the presence of TNF-alpha. The ED50 for this effect is typically 5 - 30 ng/mL. 2、Recombinant Human IL-18 Protein (rp147444) stimulates cell proliferation of the CTLL-2 mouse cytotoxic T cell line. The ED50 for this effect is typically 0.27 ng/mL.

Recombinant Human Galectin-1 Protein
- 种属: 人(Human)
- Accession #: P09382.2
- 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 biological activity determined by a chemotaxis bioassay using human blood monocytes is in a concentration range of 1.0-10 ng/ml.
-
Recombinant Bovine CD4 Protein
- 种属: 牛(Bovine)
- Accession #: F1MJK4
- 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 by the ability of the immobilized protein to support the adhesion of NIH‑3T3 mouse embryonic fibroblast cells.The ED50for this effect is 0.1-0.5 μg/mL after a 1 hour incubation at37 °C.Optimal dilutions should be determined by each laboratory for each application.
