描述

IL-6 Protein is a multifunctional cytokine secreted by both immune and non-immune cells, and belongs to the interleukin family. IL-6 Protein plays a key role in immune responses, inflammatory reactions and other processes. IL-6 Protein, Mouse is a recombinant IL-6 protein expressed by E. coli without a tag[1][2][3].

研究背景

IL-6 是由免疫细胞 (如 T 细胞、B 细胞、巨噬细胞) 及非免疫细胞 (如成纤维细胞、内皮细胞、肝细胞) 分泌的多功能细胞因子。IL-6 通过与受体结合传递信号。IL-6 是应对感染和组织损伤时快速短暂产生的细胞因子,通过刺激急性期反应、造血和免疫反应参与宿主防御,其失调可引发慢性炎症和自身免疫病。IL-6 在炎症初始阶段经血液运输至肝脏诱导多种急性期蛋白合成,还参与血清铁、锌水平调节及血小板释放,其在免疫应答中可促进 Th17 分化、抑制 Treg 分化,影响免疫耐受[1][2][3]

体外研究
(In Vitro)

IL-6 蛋白 (Mouse; 25 ng/mL; 24 h) 在原代小鼠软骨细胞中可促进炎症因子 MCP-1、MMP-3、CCL5、CXCL12 产生和肥大标志物 COL10A1、RUNX2 表达。机制涉及对 JAK2/STAT3 通路的激活[3]

体内研究
(In Vivo)

IL-6 蛋白 (Mouse; 0.3 μg/kg; 关节内注射; 单次) 在大鼠中可导致脊髓过度兴奋[3]

生物活性

1.The ED50 is <0.02 ng/mL as measured by murine 7TD1 cells, corresponding to a specific activity of >5 × 107 units/mg.
2. Measured by its binding ability in a functional ELISA. When Recombinant Mouse IL-6 Protein is immobilized at 5 μg/mL (100 µL/well) can bind Biotinylated Recombinant Mouse IL-6 R alpha. The ED50 for this effect is 20-156 ng/mL.

  • Immobilized Mouse IL-6, His Tag at 5 μg/mL (100 μL/well) can bind Biotinylated Mouse IL-6 R alpha that produces 50% of the optimal binding response is found to be approximately 117.5 ng/mL.

组分

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4 or 50 mM Tris-HCL, 200 mM NaCl, 500 mM arginine, pH 8.0 or PBS, pH 7.4, 8% trehalose.

内毒素含量

<1 EU/μg, determined by LAL method.

复溶方法

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).

保存条件 & 期限

Stored at -20°C for 2 years from date of receipt. 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.

运输条件

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
