ActiveMax® Human VEGF110 (VE0-H5212) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Arg 136 (Accession # NP_001165097).
Predicted N-terminus: Ala 27
This protein carries no "tag".
The protein has a calculated MW of 12.6 kDa. As a result of glycosylation, The protein migrates as 18-20 kDa under reducing (R) condition and 40-45 kDa (homodimer) under non-reducing (NR) condition on SDS-PAGE gel.
This product does not contain a heparin binding domain, and therefore doesn't bind with heparin.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
>95% as determined by SEC-HPLC.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Amino Acid Sequence
Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF) and VEGF-A, and is a member of the platelet-derived growth factor (PDGF)/vascular endothelial growth factor (VEGF) family and encodes a protein that is often found as a disulfide linked homodimer. This protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Alternatively spliced transcript variants, encoding either freely secreted or cell-associated isoforms, have been characterized. Alternatively spliced isoforms of 110,121,145,165,183,189 and 206 amino acids in length are expressed in humans.
