 常见问题解答
Q:

两次反复冻融的具体操作方法是什么,包括冷冻和解冻的温度以及持续时间是多少。

A:
两次反复冻融的具体操作如下:将经PBS均质处理的样品在-20℃下保存一夜,然后置于室温下充分溶解。这是第一次冻融。接着,将样品在-80℃冻结或在-20℃下过夜,然后再次在室温下充分溶解。这是第二次冻融。整个解冻过程建议在冰上进行。在随后的操作中,您只需要按照说明进行即可。
Q:

在组织均质化过程中是否应该添加蛋白酶和磷酸酶抑制剂?

A:
如果您想进行组织均质化处理,首先应该考虑组织样品的差异性和均质性。我们建议先进行梯度稀释的预实验。其次,在组织样品处理过程中应使用PBS缓冲液。对于CSB-E04756m,不要在组织处理过程中添加蛋白酶,因为这种物质会加速蛋白质降解。可以添加磷酸酶抑制剂,一般比例为1:100。具体用量应结合磷酸酶抑制剂说明书中的建议用量。
Q:

用于组织匀浆所需的PBS的PH值是多少?

A:
组织样本处理使用PBS时通常pH应为7.2-7.4.
Q:

我们是否应该将计算结果统一定为每个样本的总蛋白质含量?

A:
您可以选择不进行总蛋白的定量,直接使用pg/mL来表示结果。您也可以选择对总蛋白进行定量,然后使用pg/mg来表示结果。这完全取决于您对检测结果的要求。

  • 最新研究进展:
    VEGF-A(vascular endothelial growth factor-A)是一种重要的血管生成促进因子,可促进内皮细胞增殖和血管新生。其最新研究进展包括:在肝癌和肾癌中的高表达与预后不良相关,抗VEGF-A药物如贝伐单抗已被用于这些肿瘤的治疗。此外,最近的研究还发现VEGF-A在血液和肾脏疾病中也起着重要的作用,如肾小球肾炎、糖尿病肾病等。
  • 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. May play a role in increasing vascular permeability during lactation, when increased transport of molecules from the blood is required for efficient milk protein synthesis. 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.
