蛋白名称：IL2蛋白, IL2 protein
蛋白构建：A DNA sequence encoding the rat IL2 (P17108) (Ala 21-Gln 155) was expressed and purified, with an initial Met at the N-terminus.
表达宿主：E. coli
蛋白纯度：> 95 % as determined by SDS-PAGE
蛋白活性：1. Measured by its ability to bind recombinant human IL2Ra-Fc (Cat:10165-H02H) in a functional ELISA. 2. Measured in a cell proliferation assay using CTLL2. The ED50 for this effect is typically 0.5-3 ng/mL.
蛋白内毒素：Please contact us for more information.
预测N端：Met
蛋白分子量：The recombinant rat IL2 consisting of 136 amino acids and has a calculated molecular mass of 15.6 kDa. It migrates as an approximately 15 kDa band in SDS-PAGE under reducing conditions.
蛋白NP号：P17108
蛋白氨基酸序列：Ala21-Gln155
蛋白标签：Native
蛋白保存条件：Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

文献和实验Antibody-IL2 Fusion Proteins for Tumor Targeting
as part of an antibody-cytokine fusion protein to the tumor tissue by a single chain fragment of variable regions (scFv) antibody recognizing a tumor-associated antigen. IL2 can moreover be combined with IL12 in a dual cytokine fusion protein, which simultaneously

基础。 传统的NK细胞扩增技术是在NK细胞培养体系中添加IL2、IL15等细胞因子以促进NK细胞增殖，但由于扩增效率不高且纯度不够未能得到广泛应用。近年来，有人采用基因工程的方法在K562细胞上同时表达IL-15、CD137L 等分子, 并以此细胞来刺激NK细胞的增殖。IL-15和CD137L联合刺激是PBMC 中NK细胞特异性扩增的基础：作为膜蛋白，通过细胞间的接触刺激，用以诱导NK细胞扩增。IL15能够促进NK细胞的分化成熟，而IL21能够联合IL15分子促进NK细胞的分化成熟，所以本研究在稳定
