    • 产品描述:

      The rat VEGFR-1 ELISA Kit is engineered for accurate measurement of rat VEGFR-1 levels from samples including serum, plasma, or tissue homogenates. It uses the Sandwich-ELISA mechanism in combination with the enzyme-substrate chromogenic reaction to measure the VEGFR-1 content in the sample. The color intensity is positively correlated with VEGFR-1 content in the sample. The VEGFR-1 concentration can be calculated according to the standard curve. This kit is tested with high sensitivity, strong specificity, good linearity, high precision and recovery, as well as lot-to-lot consistency.

      VEGFR-1, also called Flt-1, is the exclusive VEGFR present on the surface of monocytes and mediates a chemotactic response to VEGF-A and tissue factor induction. In myeloid cells, VEGFR-1 mediates monocyte migration and has a regulatory role in the development of inflammatory diseases such as rheumatoid arthritis and arteriosclerosis. In vascular smooth muscle cells (SMCs), VEGFR-1 is inducibly expressed by vascular injury and participates in neointimal development. VEGFR-1 expression has frequently been detected in melanoma and is also found in other cancer types. Upon activation by VEGF-A or PlGF, VEGFR-1 promotes cell survival, migration, invasiveness, and chemoresistance of melanoma cells.

    • 功能:
      Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFB and PGF, and plays an essential role in the development of embryonic vasculature, the regulation of angiogenesis, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. Acts as a positive regulator of postnatal retinal hyaloid vessel regression. May play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells. Can promote endothelial cell proliferation, survival and angiogenesis in adulthood. Its function in promoting cell proliferation seems to be cell-type specific. Promotes PGF-mediated proliferation of endothelial cells, and proliferation of some types of cancer cells, but does not promote proliferation of normal fibroblasts. Has very high affinity for VEGFA and relatively low protein kinase activity; may function as a negative regulator of VEGFA signaling by limiting the amount of free VEGFA and preventing its binding to KDR. Modulates KDR signaling by forming heterodimers with KDR. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, leading to the activation of phosphatidylinositol kinase and the downstream signaling pathway. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Phosphorylates SRC, YES1 and PLCG, and may also phosphorylate CBL. Promotes phosphorylation of AKT1 and PTK2/FAK1.
