分子別名(Synonym)
ICAM1,BB2,CD54,P3.58
表達區(qū)間及表達系統(tǒng)(Source)
Human ICAM-1, Fc Tag (IC1-H5250) is expressed from human 293 cells (HEK293). It contains AA Gln 28 - Glu 480 (Accession # AAH15969).
Predicted N-terminus: Gln 28
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 75.7 kDa. The protein migrates as 90-120 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 51 mM Tris, 100 mM Glycine, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景(Background)
細胞間粘附分子1(ICAM-1)也稱為分化簇54(CD54),是免疫球蛋白超家族的成員,是一種細胞表面糖蛋白,通常在內(nèi)皮細胞和免疫系統(tǒng)細胞上以低濃度表達。該基因編碼的蛋白質(zhì)是一種細胞間粘附分子,以低濃度持續(xù)存在于白細胞和內(nèi)皮細胞的膜中。在細胞因子刺激下,濃度大大增加。ICAM-1可由白細胞介素-1(IL-1)和腫瘤壞死因子α(TNFα)誘導,并由血管內(nèi)皮、巨噬細胞和淋巴細胞表達。ICAM-1是白細胞上發(fā)現(xiàn)的受體LFA-1(整合素)的配體。當被激活時,白細胞通過ICAM-1/LFA-1與內(nèi)皮細胞結(jié)合,然后轉(zhuǎn)移到組織中。ICAM-1與蛛網(wǎng)膜下腔出血(SAH)有關(guān)。許多研究表明,蛛網(wǎng)膜下腔出血患者的ICAM-1水平明顯高于對照組。呼吸道上皮細胞表達的ICAM-1也是鼻病毒的結(jié)合位點,鼻病毒是最常見感冒的病原體。
