Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against 25 mM HEPES and 150 mM NaCl, pH 7.0.

Endotoxin Level
<1.0 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Mouse VEGF164 (P.pastoris-expressed) (rMuVEGF164) to 100 µg/mL using ddH2O.

Storage & Stability
Lyophilized recombinant Mouse VEGF164 (P.pastoris-expressed) (rMuVEGF164) is stored at -20°C. After reconstitution, it is stable at 4°C for 4 weeks 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
VEGF164 (165) is a proinflammatory isoform. VEGF164 was found to be significantly more potent at inducing inflammation. In vivo blockade of VEGF receptor (VEGFR)-1 significantly suppressed VEGF164-induced corneal inflammation. In vitro, VEGF164 more potently stimulated intracellular adhesion molecule (ICAM)-1 expression on endothelial cells, an effect that was mediated by VEGFR2. VEGF164 was also more potent at inducing the chemotaxis of monocytes, an effect that was mediated by VEGFR1. In an immortalized human leukocyte cell line, VEGF164 was found to induce tyrosine phosphorylation of VEGFR1 more efficiently[1]. VEGF164 is an important isoform in the pathogenesis of early diabetic retinopathy[2].
