Background
VEGF121 is the second most abundant splice variant of VEGF-A (1,2). VEGF121 is produced by endothelial cells, macrophages, T-cells and other cell types. VEGF121 is involved in angiogenesis, vascular endothelial cell survival, growth, migration and vascular permeability (1). VEGF121 expression is induced by hypoxia, inflammatory cytokines and through oncogene products in tumors (1-3). VEGF121 binds to VEGFR1 and VEGFR2 receptor tyrosine kinases (1). Binding of VEGF121 to VEGFR1 and VEGFR2 leads to activation of pathways involving PI3K/AKT, P38 MAPK, and FAK (1). VEGF plays a key role in tumor angiogenesis in many cancers (2).
Endotoxin
Less than 0.01 ng endotoxin/1μg hVEGF121.
Purity
>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hVEGF121. All lots are greater than 98% pure.
Source / Purification
Recombinant human VEGF121 (hVEGF121) Ala207-Arg327 (Accession #NP_001020541.2) was expressed in human 293 cells at Cell Signaling Technology.
Bioactivity
The bioactivity of recombinant hVEGF121 was determined in a cell proliferation assay using HUVEC. The ED50 of each lot is between 0.5-2 ng/ml.
