Description
Vascular Endothelial Growth Factor (VEGF), was initially purified from media conditioned by normal bovine pituitary folliculo-stellate cells and by a variety of transformed cell lines as a mitogen specific for vascular endothelial cells. It was subsequently found to be identical to an independently discovered vascular permeability factor (VPF), which was previously identified in media conditioned by tumor cell lines based on its ability to increase the permeability of capillary blood vessels. Three mouse cDNA clones, which arise through alternative splicing and which encode mature mouse monomeric VEGF having 120, 164, or 188, amino acids, respectively, have been identified. Two receptor tyrosine kinases (RTKs), Flt-1 and Flk-1 (the mouse homologue of human KDR), both members of the type III subclass of RTKs containing seven immunoglobulin-like repeats in their extracellular domains, have been shown to bind VEGF with high affinity. The roles of the homodimers of KDR, Flt, and the heterodimer ofKDR/Flt in VEGF signal transduction remain to be elucidated.In vivo, VEGF has been found to be a potent angiogenesis inducer.
M.W.
Recombinant, mouse VEGF120, is a 28.4 kDa disulfide-linked homodimeric protein consisting of two 121 amino acid polypeptide chains.
Purity
>96% by SDS-PAGE and HPLC analyses.
Endotoxin Level
Less than 0.2EU/ug of recombinant mouse VEGF120 as determined by LAL method.
Specific Activity
Measured by its ability to induce proliferation of human umbilical vein endothelial cells. The ED50 for this effect is typically 2 - 4 ng/mL, corresponding to a specific activity of > 2.5x105 units/mg.
Storage
This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 C to -70 C. Avoid repeated freeze/thaw cycles.
Formulation
Lyophilized from a 0.2um filtered solution in PBS, pH 7.4.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20 C. Further dilutions should be made in appropriate buffered solutions.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage
This material is for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
