IL-3 蛋白, Human

IL-3 Protein, Human is a multilineage hematopoietic cytokine with promising effects on platelet and neutrophil counts and special usefulness in patients with secondary hematopoietic failure.

白细胞介素-3 (IL-3) 是属于造血生长因子家族的糖蛋白，在临床前体外和体内研究中已表现出多谱系活性。重组人白细胞介素 3 (rhIL-3) 通过重组人粒细胞集落刺激因子 (rhG-CSF) 增强外周血祖细胞的动员^[1]。人白细胞介素 3 (hIL-3) 是一种多能造血细胞因子，由有丝分裂原和抗原激活的角质形成细胞、T 淋巴细胞、肥大细胞、NK 细胞、单核细胞和内皮细胞产生。造血祖细胞在hIL-3蛋白的帮助下增殖并分化为成熟红细胞、肥大细胞、巨核细胞和粒细胞。hIL-3 蛋白的潜在用途已在骨髓移植、血液恶性肿瘤、血细胞减少症、再生障碍性贫血和各种类型的癌症等各种临床应用中得到广泛测试^[2]。

The ED₅₀ is <0.6 ng/mL as measured by TF-1 cells, corresponding to a specific activity of >1.67 × 10⁷ units/mg.

无菌粉末

Lyophilized after extensive dialysis against PBS or 50 mM Tris-HCL, 300 mM NaCl, 200 mM arginine, pH 8.0.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
