通用注释

亚单元:

Homodimer; disulfide-linked. Also found as heterodimer with PGF (By similarity). Interacts with NRP1 (PubMed:26503042).

功能:

Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. NRP1/Neuropilin-1 binds isoforms VEGF-165 and VEGF-145. Isoform VEGF165B binds to KDR but does not activate downstream signaling pathways, does not activate angiogenesis and inhibits tumor growth. Binding to NRP1 receptor initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development.

亚细胞位置:

Secreted VEGF121 is acidic and freely secreted. VEGF165 is more basic, has heparin-binding properties and, although a signicant proportion remains cell-associated, most is freely secreted. VEGF189 is very basic, it is cell-associated after secretion and is bound avidly by heparin and the extracellular matrix, although it may be released as a soluble form by heparin, heparinase or plasmin.

人血管内皮生长因子A(VEGFA)重组蛋白是否是无菌的？

蛋白试剂瓶和蛋白保存液是经过高压灭菌的，但也不能保证蛋白是完全无菌的。如果要求蛋白是无菌的，可以用0.2微米的滤器对蛋白进行过滤。

[2].

人血管内皮生长因子A(VEGFA)重组蛋白的保存缓冲液是什么？

纯化后的蛋白保存在PBS（58mM Na2HPO4, 17mM NaH2PO4, 68mM NaCl, pH7.4）里，并往里面加入500mM咪唑和10%甘油。

[3].

怎样确定人血管内皮生长因子A(VEGFA)重组蛋白的浓度？

蛋白浓度的确定没有一个统一的标准，这主要取决于蛋白的氨基酸序列。伊艾博是根据不同测试的组合来测定蛋白浓度。考马斯亮蓝法、BCA法、氨基酸序列和氨基酸全序列分析法等都用来测定蛋白浓度。

[4].

人血管内皮生长因子A(VEGFA)重组蛋白蛋白保存条件是怎样的？

蛋白应保存在 -20℃或 -80℃条件下，为了避免反复冻融，可以将蛋白分装成小份保存。

[5].

人血管内皮生长因子A(VEGFA)重组蛋白是否可以用于活体实验？

重组蛋白没有用于任何的活体实验，因此蛋白的活性和半衰期是不确定的。

[6].

人血管内皮生长因子A(VEGFA)重组蛋白的保质期是多久？

在适当的保存条件下，从购买之日起蛋白可以稳定保存6-12个月。适当的保存条件是:蛋白保存在-20°C o或 -80℃，保证蛋白的保存浓度高于0.1mg/ml，限制蛋白反复冻融的次数。我们公司常规的质量检测保证所有产品在销售时都有可接受的生物活性。但是我们不能控制终端用户蛋白的保存条件。如果产品在有效期内出现问题，请联系我们的技术支持。

[7].

你们蛋白和抗体的报价是怎么样的？

我们将根据你需要的蛋白和抗体的大小进行报价。

[8].

人血管内皮生长因子A(VEGFA)重组蛋白是否能够提供蛋白片段？

我们现有的人的蛋白的序列可以有很多。你可以选择你感兴趣的靶向部分，我们将会按您的需求提供蛋白和抗体。

[9].

人血管内皮生长因子A(VEGFA)重组蛋白的货期或发货时间一般是多长？

具体指标的货期需要确定。最快一周，最长可能一个月。
