Human CD160 Protein, His Tag

分子別名（Synonym）

CD160,BY55,NK1,NK28

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Human CD160, His Tag (BY5-H5229) is expressed from human 293 cells (HEK293). It contains AA Ile 27 - Ser 159 (Accession # O95971-1).

Predicted N-terminus: Ile 27

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

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 16.7 kDa. The protein migrates as 25-28 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）

>90% as determined by SDS-PAGE.

制劑（Formulation）

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

背景（Background）

CD160抗原也被稱為自然殺傷細(xì)胞受體BY55，是一種27kDa的糖蛋白，含有1個(gè)Ig樣V型（免疫球蛋白樣）結(jié)構(gòu)域。其表達(dá)與外周血NK細(xì)胞和具有細(xì)胞溶解效應(yīng)活性的CD8 T淋巴細(xì)胞密切相關(guān)。CD160在細(xì)胞表面表達(dá)為緊密二硫鍵連接的多聚體。在組織中，CD160在所有腸上皮內(nèi)淋巴細(xì)胞上表達(dá)。CD160顯示出與經(jīng)典和非經(jīng)典MHC I類分子結(jié)合的廣泛特異性。當(dāng)在血管內(nèi)皮細(xì)胞上表達(dá)時(shí)，CD160傳播抗血管生成信號并促進(jìn)細(xì)胞凋亡。
