Animal-Free IL-3 蛋白, Mouse (His)

IL-3 protein is secreted by T lymphocytes, mast cells and osteoblasts. It plays an important regulatory role in hematopoietic progenitor cells and stimulates mature basophils, eosinophils and monocytes. In addition to hematopoiesis, it supports neuronal cell proliferation, survival, and bone homeostasis by inhibiting osteoclast differentiation. Animal-Free IL-3 Protein, Mouse (His) is the recombinant mouse-derived animal-FreeIL-3 protein, expressed by E. coli , with C-His labeled tag. The total length of Animal-Free IL-3 Protein, Mouse (His) is 134 a.a., with molecular weight of ~16.04 kDa.

细胞因子 IL-3 主要由活化的 T 淋巴细胞、肥大细胞和成骨细胞分泌，在控制造血祖细胞向谱系限制细胞的产生和分化中发挥着至关重要的作用。此外，IL-3 可刺激成熟的嗜碱性粒细胞、嗜酸性粒细胞和单核细胞，促进其功能激活。除造血功能外，IL-3 还有助于神经细胞增殖和存活，并通过防止 NF-kappa-B 核易位和激活来抑制破骨细胞分化，从而参与骨稳态。从机制上讲，IL-3 通过由 IL3RA 亚基和信号转导亚基 IL3RB 组成的受体发挥其生物效应，导致 JAK2 激酶活性快速激活以及随后 STAT5 介导的转录编程。此外，IL-3 作为单体，通过激活 PI3K/AKT 和 ERK 介导的途径，有助于非造血系统中氧化应激下的细胞存活。

Measure by its ability to induce NFS-60 cells proliferation. The ED₅₀ for this effect is <85 pg/mL. The specific activity of recombinant mouse IL-3 is approximately >1x10⁷ IU/mg.
