VEGF Protein (AA 27-191) (Biotin)

Catalog No. ABIN2181906

Product Details

Target: VEGF (Vascular Endothelial Growth Factor (VEGF))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 27-191

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This VEGF protein is labelled with Biotin.

Brand: MABSol®,UltraLys

Sequence: AA 27-191

Specificity: The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Characteristics: The product does NOT contain any epitope tags. The protein has a calculated MW of 19 kDa (monomer). The protein migrates as 24 kDa (monomer) on a SDS-PAGE gel under reducing (R) condition due to glycosylation and 43-50 kDa under non-reducing (NR) condition.

Purity: >95 % as determined by reduced SDS-PAGE.

Sterility: 0.22 μm filtered

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Application Details

Comment:

A chemically labeled biotinylated protein with ultra sensitivity.
The product is produced using a chemical labeling approach. The primary amines in the side chains of lysine residues and the N-terminus of protein are conjugated with biotins.
Chemical labeling usually results in multiple biotin attachment on a single protein molecule, which could potentially lead to higher detection sensitivity.

Restrictions: For Research Use only

Background: VEGF165 is the most abundant splice variant of VEGF-A. VEGF165 is produced by a number of cells including endothelial cells, macrophages and T cells. VEGF165 is involved in angiogenesis, vascular endothelial cell survival, growth, migration and vascular permeability. VEGF gene expression is induced by hypoxia, inflammatory cytokines and oncogenes. VEGF165 binds to heparan sulfate and is retained on the cell surface and in the extracellular matrix. VEGF165 binds to the receptor tyrosine kinases, VEGFR1 and VEGFR2. VEGF165 is the only splice variant that binds to co-receptors NRP-1 and NRP-2 that function to enhance VEGFR2 signaling. Binding of VEGF165 to VEGFR1 and VEGFR2 leads to activation of the PI3K/AKT, p38 MAPK, FAK and paxillin. VEGF plays a key role in tumor angiogenesis in many cancers.
