Vascular Endothelial Growth Factor (VEGF) is a potent mediator of angiogenesis and vasculogenesis, playing a crucial role in both embryonic development and adult physiology. The recombinant form of VEGF, specifically the mouse variant with a His tag, is widely used in research to study its biological functions and therapeutic potential.
The recombinant mouse VEGF protein with a His tag is typically expressed in HEK 293 cells, ensuring high purity and biological activity. The His tag, a sequence of histidine residues, facilitates the purification of the protein through affinity chromatography. This recombinant protein is often produced with a purity greater than 95% and an endotoxin level of less than 1 EU/µg, making it suitable for various experimental applications .
VEGF is essential for the proliferation, migration, and survival of endothelial cells. It binds to specific receptors on the surface of these cells, such as VEGFR-2 (Flk-1/KDR) and VEGFR-3 (Flt4), triggering a cascade of signaling events that promote angiogenesis. In addition to its role in blood vessel formation, VEGF also increases vascular permeability, which is critical during wound healing and in pathological conditions like tumor growth .
Recombinant mouse VEGF with a His tag is used in a variety of research applications, including:
