Reconstitution Reconstitute the lyophilized recombinant Rat VEGF165 (CHO-expressed) (rRtVEGF165) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Rat VEGF165 (CHO-expressed) (rRtVEGF165) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Vascular endothelial growth factor (VEGF or VEGFA) is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is a member of the PDGF family that is characterized by the presence of eight conserved cysteine residues and a cystine knot structure[1]. VEGF165 appears to be the most abundant and potent isoform, followed by VEGF121 and VEGF189[1][2]. VEGF165 binds the semaphorin receptor, Neuropilin1 and promotes complex formation with VEGF R2[3]. |
