| Stability & Storage | Shipped on wet ice. For long term storage, the product should be stored ≤ -20℃. Please avoid repeated freeze-thaw cycles after reconstitution. 36 months from date of receipt, -20 to -70℃ as supplied. 1 month, 2 to 8℃ under sterile conditions after reconstitution. 3 months, -20 to -70℃ under sterile conditions after reconstitution. |
| Precautions | Recombinant Human VEGF 165 is for research use only and not for use in diagnostic or therapeutic procedures. |
| Vascular Endothelial Growth Factor is a sub-family of growth factors produced by cells, which stimulates vasculogenesis and angiogenesis. VEGF's normal function is to create new blood vessels during embryonic development, new blood vessels after injury, muscle following exercise, and new vessels (collateral circulation) to bypass blocked vessels. VEGF production can be induced in cells that are not receiving enough oxygen. VEGF165 appears to be the most abundant and potent isoform, followed by VEGF121 and VEGF189. In addition, it shares 88 % a.a. with corresponding regions of mouse and rat, 96 % with porcine, 95 % with canine, and 93 % with feline, equine and bovine VEGF, respectively. Recombinant human VEGF165 contains 165 amino acids residues and it is a disulfide-linked homodimer. |
