分子別名(Synonym)
CD70,CD27LG,TNFSF7,TNFSF7G,CD27L
表達區(qū)間及表達系統(tǒng)(Source)
Human CD27 Ligand Protein, His,Flag Tag (CDL-H52Da) is expressed from human 293 cells (HEK293). It contains AA Ser 52 - Pro 193 (Accession # P32970-1 ) trimer Design.
Predicted N-terminus: His
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus, followed by a flag tag.
The protein has a calculated MW of 49.3 kDa. The protein migrates as 50-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) 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.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
分化簇70(CD70)也稱為CD27配體(CD27L/CD27LG)、TNFSF7、TNFSF7G,是屬于TNF超家族(TNFSF)的II型跨膜糖蛋白,是活化的T和B淋巴細胞以及成熟樹突狀細胞上發(fā)現(xiàn)的表面抗原。CD70與其受體CD27的結(jié)合誘導(dǎo)了T細胞的啟動、效應(yīng)器功能、分化和記憶形成,因此參與了包括T細胞活化、共刺激T細胞增殖以及細胞溶解性T細胞生成在內(nèi)的生物過程。T細胞上的CD70提供T細胞增殖、克隆擴增和促進效應(yīng)T細胞形成所需的共刺激信號。小鼠B細胞上的CD70已被證明可以抑制活化的B細胞向漿細胞的終末分化,并增強對記憶B細胞反應(yīng)的承諾。CD70誘導(dǎo)NK細胞增殖和IFNγ產(chǎn)生。
