蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 16.8 kDa. The protein migrates as 20-27 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 0.1 EU per μg by the LAL method.
无菌(Sterility)
Negative
支原体(Mycoplasma)
Negative.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
胸腺基质淋巴细胞生成素(TSLP)是一种上皮细胞衍生的细胞因子,参与炎症性皮肤病的病理过程,并在上皮细胞中广泛表达。人TSLP cD编码一个159个氨基酸(aa)残基的前体蛋白,具有28个aa的信号序列(4,5)。人类TSLP已被证明可以发展非损伤性中枢耐受,放大上皮诱导的类别转换,诱导特应性疾病,并维持肠道非炎症环境。在对人TSLP有反应的多种细胞中,CD11c+树突状细胞是最明显的靶细胞。
