蛋白結構(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.
內毒素(Endotoxin)
Less than 0.01 EU per μg by the LAL 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(Background)
VEGF165是VEGF-A最豐富的剪接變體。VEGF165由許多細胞產生,包括內皮細胞,巨噬細胞和T細胞。VEGF165參與血管生成,血管內皮細胞存活,生長,遷移和血管通透性。VEGF基因表達由缺氧,炎性細胞因子和癌基因誘導。VEGF165與硫酸乙酰肝素結合并保留在細胞表面和細胞外基質中。VEGF165與受體酪氨酸激酶VEGFR1和VEGFR2結合。VEGF165是唯一與共受體NRP-1和NRP-2結合的剪接變體,其功能是增強VEGFR2信號傳導。VEGF165與VEGFR1和VEGFR2的結合導致PI3K/AKT,p38 MAPK,FAK和樁蛋白的激活。VEGF在許多癌癥的腫瘤血管生成中起關鍵作用。
