CD40-L, Tumor necrosis factor ligand superfamily member 5, TNF-related activation protein, TRAP, T cell antigen Gp39, CD154 antigen, sCD40, IGM, IMD3, HIGM1, T-BAM, TNFSF5, hCD40L.

CD40L or CD154 is a membrane glycoprotein and differentiation antigen expressed on the surface of T-cells. The CD40 ligand stimulates B-cell proliferation and secretion of all immunoglobulin isotypes in the presence of cytokines . CD40 ligand has been shown to induce cytokine production and tumoricidal activity in peripheral blood monocytes. It also costimulates proliferation of activated T-cells and this is accompanied by the production of IFN-gamma , TNF-alpha , and IL2 .

CD40L 或 CD154 是在 T 细胞表面表达的膜糖蛋白和分化抗原。 CD40 配体在细胞因子存在的情况下刺激 B 细胞增殖和所有免疫球蛋白同种型的分泌。 CD40 配体已显示在外周血单核细胞中诱导细胞因子产生和杀肿瘤活性。 它还共同刺激活化 T 细胞的增殖，并伴随着 IFN-γ、TNF-α 和 IL2 的产生。

sCD40 Mouse Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 149 amino acids and having a molecular mass of 16409 Dalton.
The sCD40 is purified by proprietary chromatographic techniques.

在大肠杆菌中产生的 sCD40 Mouse Recombinant 是一种非糖基化的多肽链，含有 149 个氨基酸，分子量为 16409 道尔顿。
sCD40 通过专有的色谱技术进行纯化。

Escherichia Coli.

Sterile Filtered White lyophilized powder.

Lyophilized from a sterile concentrated solution with 10mM Sodium Phosphate pH=7.5.

It is recommended to reconstitute the lyophilized sCD40 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized sCD40 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CD154 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

冻干的 sCD40 虽然在室温下可稳定保存 3 周，但应在 -18°C 以下干燥储存。 重组后，CD154 应在 4°C 下储存 2-7 天，以备将来在 -18°C 以下使用。
对于长期储存，建议添加载体蛋白。
请防止冻融循环。

Greater than 98.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.

The sequence of the first five N-terminal amino acids was determined and was found to be Met-Gln-Arg-Gly-Asp.

The ED50 as determined by its ability to induce MIP-1 alpha & TNF-alpha from mouse splenocytes was found to be 0.1µg/ml corresponding to a Specific Activity of 10,000IU/mg.
