Recombinant Human Vascular Endothelial Growth Factor 121, His-tagged

• Cat.No.: VEGFA-130H
• Product Overview: Recombinant VEGF121 protein was expressed in E.coli and purified by using conventional chromatography techniques, 16.3 kDa (142aa).

Specification

• Cat. No.: VEGFA-130H
• Description: Vascular endothelial growth factor (VEGF) is homodimeric, heparin-binding glycoprotein involved in both angiogenesis and vasculogenesis. VEGF is expressed as multiple alternately spliced isoforms of VEGF121, 165, 189 and 206. VEGF binds to the receptor tyrosine kinases VEGF R1 (Flt-1) and VEGF R2 (KDR/Flk-1) to activate signal transduction and regulate both physiological and pathological angiogenesis.
