ILDR2產(chǎn)品信息

英文名稱：Immunoglobulin-like domain-containing receptor 2

中文名稱：免疫球蛋白樣結(jié)構(gòu)域受體2

靶點(diǎn)別稱：ILDR2,C1orf32

物種：Human

標(biāo)簽：Fc Tag

屬性：Protein

標(biāo)記：Unconjugated

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human ILDR2, Fc Tag (IL2-H5259) is expressed from human 293 cells (HEK293). It contains AA Leu 21 - Glu 186 (Accession # Q71H61-1).

Predicted N-terminus: Leu 21

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 45.1 kDa. The protein migrates as 45-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>95% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

This product is stable after storage at:

-20°C to -70°C for 12 months in lyophilized state;

-70°C for 3 months under sterile conditions after reconstitution.

背景（Background）

ILDR2屬于免疫球蛋白超家族。可能參與脂質(zhì)穩(wěn)態(tài)和ER應(yīng)激途徑。ILDR2是一種新型的B7樣蛋白，具有強(qiáng)大的T細(xì)胞抑制活性，在免疫細(xì)胞和免疫特權(quán)和炎癥組織中表達(dá)。由ILDR2胞外結(jié)構(gòu)域和Fc片段組成的融合蛋白與活化T細(xì)胞上的推定對(duì)應(yīng)物結(jié)合，在膠原誘導(dǎo)的關(guān)節(jié)炎模型中顯示出有益作用，并消除了巨噬細(xì)胞和細(xì)胞因子刺激的T細(xì)胞自體滑膜樣共培養(yǎng)物中促炎細(xì)胞因子和趨化因子的產(chǎn)生?？傊?，這些發(fā)現(xiàn)表明ILDR2是一種新的T細(xì)胞負(fù)調(diào)控因子，在免疫相關(guān)疾病的發(fā)展中具有潛在作用，包括自身免疫和癌癥。
