該產(chǎn)品在嚴(yán)格的質(zhì)量控制體系下生產(chǎn),包含無(wú)菌檢測(cè)及內(nèi)毒素檢測(cè)等全套測(cè)試。產(chǎn)品性能經(jīng)嚴(yán)謹(jǐn)驗(yàn)證,確保其在細(xì)胞培養(yǎng)應(yīng)用及臨床前研究階段其他用途中的兼容性。
GMP-VE5H23是VE5-H4210蛋白的GMP版本,二者性能特征完全一致,可確保使用者從早期臨床前階段到后期臨床試驗(yàn)階段的無(wú)縫銜接。
蛋白結(jié)構(gòu)(Molecular Characterization)

This protein carries no "tag".
The protein has a calculated MW of 19.2 kDa. The protein migrates as 24 kDa±3 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 0.01 EU per μg by the LAL method / rFC method.
宿主蛋白殘留(Host Cell Protein)
<0.5 ng/μg of protein tested by ELISA.
宿主核酸殘留(Host Cell DNA)
<0.02 ng/μg of protein tested by qPCR.
無(wú)菌(Sterility)
Negative
支原體(Mycoplasma)
Negative
純度(Purity)
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介紹
VEGF165是VEGF-A含量最豐富的剪接變體,由內(nèi)皮細(xì)胞、巨噬細(xì)胞和T細(xì)胞等多種細(xì)胞產(chǎn)生。該因子參與血管生成、血管內(nèi)皮細(xì)胞存活、生長(zhǎng)、遷移及血管通透性調(diào)節(jié)。VEGF基因表達(dá)受缺氧、炎癥細(xì)胞因子和癌基因誘導(dǎo)。VEGF165通過(guò)與硫酸乙酰肝素結(jié)合錨定于細(xì)胞表面及細(xì)胞外基質(zhì),并與受體酪氨酸激酶VEGFR1/VEGFR2結(jié)合。作為唯一能結(jié)合共受體神經(jīng)纖毛蛋白-1(NRP-1)和神經(jīng)纖毛蛋白-2(NRP-2)的剪接變體,VEGF165可增強(qiáng)VEGFR2信號(hào)傳導(dǎo)。其與VEGFR1/VEGFR2的結(jié)合會(huì)激活PI3K/AKT、p38 MAPK、FAK及樁蛋白(paxillin)信號(hào)通路,在多種癌癥的腫瘤血管生成中發(fā)揮關(guān)鍵作用。
