Product Description

 

Vascular endothelial growth factor C (VEGF-C) and VEGF-D constitute a subfamily of the angiogenic VEGF angiogenic factors. VEGF-C is synthesized as a 58 kDa molecule that consists of a VEGF homolgy domain (VHD) flanked by N- and C-terminal propeptides. The proprotein undergoes covalent homodimerization and stepwise proteolytic processing to generate ligands with increasing affinity for VEGF R3/Flt-4. Fully processed VEGF-C containing just the 21 kDa VHD can additionally bind and activate VEGF R2/KDR/Flk-1. Fully processed human VEGF-C shares 98% amino acid sequence identity with mouse and rat VEGF-C. VEGF-C interactions with VEGF R3 are critical for lymphangiogenesis. VEGF-C and VEGF R3 are usually co-expressed at sites with lymphatic vessel sprouting, in the embryo, and in various pathological conditions. Over-expression of VEGF-C in tumor cells induces tumoral lymphatic hyperplasia, resulting in enhanced lymph flow and metastasis to regional lymph nodes.

 

Product Properties

 

Synonyms

Flt4 ligand; Flt4-L; vascular endothelial growth factor C; Vascular endothelial growth factor-related protein; VEGFC; VEGF-C; VRPFLT4 ligand DHM

Accession

P49767

Source

HEK293 Cells-derived human VEGF-C, Thr103-Arg227 with a C-terminal polyhistidine tag.

Molecular Weight

The recombinant mature form of human VEGFC consists of 136 amino acids and has a predicted molecular mass of 15.5 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 22.5 kDa due to glycosylation.

Tag

His

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 95% by SDS-PAGE.

Biological Activity

1. Measured by its binding ability in a functional ELISA. Immobilized VEGF C-his at2μg/mL(100 μL/well) can bind VEGFR3 hFc, the EC50 of VEGFR3 hFc is 2-15 ng/mL.
2. Scatchard analysis showed the affinity constant (Kd) of recombinant human VEGF-C bound to recombinant human VEGFR3 was 1.4 nM.
3. Measured in a cell proliferation assay using human umbilical vein endothelial cells (HUVEC). The ED50 for this effect is typically 0.1-0.5 μg/mL.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. Normally 5% - 8% trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate bu
