Hu Recom VEGF-121, ACF, 1000 µg

Recombinant human Vascular Endothelial Growth Factor isoform 121 (VEGF-121) manufactured under animal component-free conditions by STEMCELL Technologies serves angiogenic and vascular differentiation workflows in regenerative medicine research. The shortest and most freely diffusible of the VEGF splice variants, VEGF-121 binds VEGFR1 and VEGFR2 on endothelial cells to drive proliferation, migration, and tube formation, making it a routine supplement in endothelial cell culture media, hematopoietic and mesenchymal stem cell expansion protocols, and 3D vascular organoid or sprouting assays. Because the protein is produced without animal-derived raw materials, it is a good fit for cell therapy pipelines, xeno-free differentiation studies, and translational work where trace contaminants must be controlled. The 1000 µg vial format provides a large stock for repeated media supplementation and concentration-titration experiments, and the lyophilized preparation is stored at -20 °C with reconstitution in PBS or media containing carrier protein. Reconstituted aliquots remain stable through several freeze-thaw cycles when handled as single-use working stocks, and endotoxin levels are reported low enough for sensitive primary endothelial culture.
