PurityImmunogen affinity purified
Purification notesThe antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated VEGFR 2. The final product is generated by affinity chromatography using a VEGFR 2 derived peptide that is phosphorylated at Tyrosines 1054 and 1059.
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab5473 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000. Detects a band of approximately 200 kDa.
1/1000. Detects a band of approximately 200 kDa.
FunctionReceptor for VEGF or VEGFC. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions.
Involvement in diseaseDefects in KDR are associated with susceptibility to hemangioma capillary infantile (HCI) [MIM:602089]. HCI are benign, highly proliferative lesions involving aberrant localized growth of capillary endothelium. They are the most common tumor of infancy, occurring in up to 10% of all births. Hemangiomas tend to appear shortly after birth and show rapid neonatal growth for up to 12 months characterized by endothelial hypercellularity and increased numbers of mast cells. This phase is followed by slow involution at a rate of about 10% per year and replacement by fibrofatty stroma.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
Contains 1 protein kinase domain.
modificationsPhosphorylated. Dephosphorylated by PTPRB. Dephosphorylated by PTPRJ at Tyr-951, Tyr-996, Tyr-1054, Tyr-1059, Tyr-1175 and Tyr-1214.

Immunofluorescence analysis of HUVEC cells labelling VEGF Receptor 2 (phospho Y1054 + Y1059) (PAnel a: green) using ab5473 at 2 ug/ml in 0.1% BSA for 3 hours at room temperature, follwed by Alexa Fluor® 488-conjugated Goat anti-rabbit IgG polyclonal at 1/2000 dilution. Pbel b: Nuclei stained with DAPI (blue), Panel c: F-actin stained with Alexa Fluor® 555 Rhodamine Phalloidin (red), Panel d: Merged images. The images were captured at 60X magnification.
Prior antibody incubation, HUVEC (Human umbilical vein endothelial cell line) cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes and blocked with 1% BSA for 1 hour at room temperature, followed by treatment with 100 ng of VEGF for 30 minutes. Assay was done on 90% confluent log phase HUVEC cells.

A 130 kDa band corresponding to VEGFR (pYpY1054/1059) was observed across cell lines tested.
Protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel, XCell SureLock™ Electrophoresis System and Novex® Sharp Pre-Stained Protein Standard.
Resolved proteins were then transferred onto a nitrocellulose membrane by over night wet transfer.
Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate.
