Recombinant Human VEGF-A/VEGF121 Protein (RP01162) | ABclonal Technology™

ABclonal Technology™ Recombinant Human VEGF-A/VEGF121 Protein (RP01162) is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ala27-Arg147) of human VEGF121 (Accession #NP_001165099.1) fused with a 6×His tag at the N-terminus. Purity: ≥ 95 % as determined by SDS-PAGE. Each lot is quality controlled to support reproducible results in research applications.

This protein is a member of the PDGF/VEGF growth factor family. It encodes a heparin-binding protein, which exists as a disulfide-linked homodimer. This growth factor induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Disruption of this gene in mice resulted in abnormal embryonic blood vessel formation. This protein is upregulated in many known tumors and its expression is correlated with tumor stage and progression. Elevated levels of this protein are found in patients with POEMS syndrome, also known as Crow-Fukase syndrome.

• Species: Human
• Expression System: HEK293 cells
• Tag: N-His
• Purity: ≥ 95 % as determined by SDS-PAGE.
• Endotoxin: < 0.1 EU/μg of the protein by LAL method.
• Bioactivity: 1.Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human VEGF121 at 1 μg/mL (100 μL/well) can bind Recombinant Human VEGFR2 with a linear range of 4-10 ng/mL.|2.Measured in a cell proliferation assay using HUVEC human umbilical vein endothelial cells. The ED₅₀ for this effect is 0.09-0.36 ng/mL.|3.Recombinant Human VEGFA(40 ng/mL) and bFGF(50 ng/mL, Cat. RP01162) induce mesoderm cells to differentiate into hematopoietic stem and progenitor cells. After 4 days induction, pebbly-like CD43+ hematopoietic stem and progenitor cells appeared in the hematogenic endothelium.
