蛋白结构(Molecular Characterization)
![1.jpg 1.jpg](/SupplyImg1/2024-08-01/6385810685003054513682418.jpg)
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 53.8 kDa. The protein migrates as 66-90 kDa under reducing (R) condition, and 130-150 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素(Endotoxin)
Less than 0.01 EU per μg by the LAL method.
无菌(Sterility)
Negative
支原体(Mycoplasma)
Negative.
纯度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景(Background)
分化簇86(CD86)也称为B淋巴细胞活化抗原B7-2,是一种I型膜蛋白,是免疫球蛋白超家族的成员,在交叉树突细胞、朗格罕斯细胞、外周血树突细胞、记忆B细胞和生发中心B细胞上组成型表达。此外,B72在单核细胞上的表达水平较低,可以通过干扰素γ上调。CD86是T细胞表面两种不同蛋白质的配体:CD28(用于自动调节和细胞间结合)和CTLA-4(用于减弱调节和细胞分离)。CD86与CD80协同作用以激活T细胞。最近的研究表明,B7-2促进了成熟APC库的产生,并促进了APC的功能和存活。此外,B7蛋白还通过激活巨噬细胞中的NF-κB信号通路参与先天免疫反应。因此,CD86被视为免疫治疗的有前景的候选者。霍奇金淋巴瘤患者的CD86+巨噬细胞是一线治疗潜在无反应的独立标志物。
