Biotinylated Human VEGF165 Protein, His,Avitag™ (HPLC verified)
分子别名(Synonym)
RP1-261G23.1, MGC70609, MVCD1, VEGFA, VPF
表达区间及表达系统(Source)
Biotinylated Human VEGF165, His,Avitag (VE5-H82Q0) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Arg 191 (Accession # P15692-4).
Predicted N-terminus: His
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 22.4 kDa (monomer). The protein migrates as 23-28 kDa (monomer) under reducing (R) condition, and 40-55 kDa (homodimer) when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
纯度(Purity)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-HPLC.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
VEGF165 是血管内皮生长因子A(VEGF-A)最丰富的剪接变体。该因子由多种细胞产生,包括内皮细胞、巨噬细胞和T细胞。
VEGF165参与血管生成(angiogenesis)、血管内皮细胞存活、生长、迁移以及血管通透性的调节。VEGF基因表达受缺氧、炎症细胞因子和癌基因的诱导。
VEGF165可结合硫酸乙酰肝素(heparan sulfate),从而被滞留在细胞表面和细胞外基质中。它能与受体酪氨酸激酶VEGFR1(血管内皮生长因子受体1) 和 VEGFR2(血管内皮生长因子受体2) 结合。值得注意的是,VEGF165是唯一能与辅助受体NRP-1(神经纤毛蛋白-1) 和 NRP-2(神经纤毛蛋白-2) 结合的剪接变体,这些辅助受体能增强VEGFR2的信号传导。
VEGF165与VEGFR1和VEGFR2的结合可激活多条信号通路,包括 PI3K/AKT、 p38 MAPK、 FAK 和 桩蛋白(paxillin)通路
VEGF在多种癌症的肿瘤血管生成中扮演关键角色。
