VEGF C Protein, Human, Recombinant (His Tag)

Product Specifications

Background

Vascular endothelial growth factor C (VEGF-C) is a member of the VEGF family. Upon biosynthesis, VEGF-C protein is secreted as a non-covalent momodimer in an anti-parellel fashion. VEGF-C protein is a dimeric glycoprotein, as a ligand for two receptors, VEGFR-3 (Flt4), and VEGFR-2. VEGF-C may function in angiogenesis of the venous and lymphatic vascular systems during embryogenesis. VEGF-C protein is over-expressed in various human cancers including breast cancer and prostate cancer. VEGF-C/VEGFR-3 axis, through different signaling pathways, plays a critical role in cancer progression by regulating different cellular functions, such as invasion, proliferation, and resistance to chemotherapy. Thus, targeting the VEGF-C/VEGFR-3 axis may be therapeutically significant for certain types of tumors.

Overview

A DNA sequence encoding the mature form of human VEGFC (NP_005420.1) (Thr103-Arg227) was expressed with a C-terminal polyhistidine tag.

Endotoxin

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

Purity

> 95 % as determined by SDS-PAGE.

Activity

1. Measured by its binding ability in a functional ELISA. Immobilized VEGF C-his (Cat:PH51671M2) at 2 μg/mL (100 μL/well) can bind VEGFR3 hFc (Cat:PH51452M4), the ECof VEGFR3 hFc (Cat:PH51452M4) 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 EDfor this effect is typically 0.1-0.5 μg/mL.

Form

Lyophilized

Buffer

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

Function

Cytokine Proteins, Growth Factor proteins, Cell Therapy proteins, Biological Target proteins

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.

Storage Conditions

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
