產品詳情

  • 產品描述：
    人血管內皮生長因子121(VEGF121)酶聯免疫試劑盒（CSB-E13709h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的VEGF121含量。VEGF121 是血管內皮生長因子（VEGF）的一種主要亞型。它在血管生成、腫瘤生長和轉移等過程中起關鍵作用。其研究機制主要聚焦于與受體結合，激活下游信號通路，促進血管內皮細胞的增殖、遷移和存活，目前是腫瘤等疾病治療的重要靶點。試劑盒檢測范圍為0.156 ng/mL-10 ng/mL，腫瘤血管生成機制研究、心血管疾病模型評估、再生醫學實驗等科研場景，體外實驗、動物模型及細胞水平的研究本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 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.
  • 相關疾病：
    Microvascular complications of diabetes 1 (MVCD1)
  • 亞細胞定位：
    Secreted. Note=VEGF121 is acidic and freely secreted. VEGF165 is more basic, has heparin-binding properties and, although a significant 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.
  • 蛋白家族：
    PDGF/VEGF growth factor family
  • 組織特異性：
    Isoform VEGF189, isoform VEGF165 and isoform VEGF121 are widely expressed. Isoform VEGF206 and isoform VEGF145 are not widely expressed. A higher level expression seen in pituitary tumors as compared to the pituitary gland.
