Vascular endothelial growth factor B (VEGF-B) is a member of the VEGF family and particularly abundant in heart and skeletal muscle.1 It is an angiogenic and neuroprotective protein that reduces hypoxic and ischemic neuronal injury.2 VEGF-B has a role in vascularization of the heart, skeletal muscles and developing bones, and in paracrine interactions between endothelial and surrounding muscle cells.3 VEGF-B also regulates lipid metabolism.4

Protein Details

>95% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human VEGF-B was determined by its binding ability in a functional ELISA. Immobilized recombinant rat Neuropilin1 at 4 μg/ml (100 μl/well) can bind recombinant human VEGFB 167 with a linear range of 0.3-20 ng/ml.
Expression Host
E. coli

State of Matter
Predicted Molecular Mass
The predicted molecular weight of Recombinant Human VEGF-B is Mr 19 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is 19-22 kDa (reducing conditions).
This recombinant protein was 0.2 μm filtered and is supplied as a solution in 35% acetonitrile (CH3CN) and 0.1% trifluoroacetic acid (TFA).
Storage and Stability
The protein should be stored at -20 - -70°C upon receipt. It may be stored at 2 - 8°C for one month. However, it is recommended to aliquot into working volumes and store at -20 - -70°C in a manual defrost freezer. Avoid repeat freeze thaw cycles.
