Product Summary for Human Phospho-VEGFR3/Flt-4 DuoSet IC ELISA
This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure tyrosine-phosphorylated human VEGF R3 / Flt-4 in cell lysates. An immobilized capture antibody specific for VEGF R3 / Flt-4 binds both phosphorylated and unphosphorylated VEGF R3 / Flt-4 . After washing away unbound material, a biotinylated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

Scientific Data Images for Human Phospho-VEGFR3/Flt-4 DuoSet IC ELISA
Figure 1. The Human Phospho-VEGF R3 DuoSet IC ELISA is more sensitive than immunoprecipitation (IP)-Western analysis
Lysates prepared from human VEGF R3 transfected NS0 cells (NS0-hVEGF R3) were diluted in a series and analyzed by (A) IP-Western blot and (B) this DuoSet IC ELISA. IPs were done using an anti-VEGF R3 monoclonal antibody and goat anti-mouse agarose. Immunoblots were incubated with a biotinylated anti-phosphotyrosine monoclonal antibody (Catalog # BAM1676) to detect phospho-VEGF R3. Bands were visualized with Streptavidin-HRP (Cat # DY998) followed by chemiluminescent detection using WesternGloTM Chemiluminescent Detection Substrate (Catalog # AR004). Human Phospho-VEGF R3 can be detected in this DuoSet IC ELISA by using approximately 10 to 15 times less lysate than is needed for a conventional IP-Western blot.
Figure 2. The specificity of the Human Phospho-VEGF R3 DuoSet IC ELISA is confirmed by receptor competition
The indicated amounts of recombinant extracellular domains of human VEGF R3 (Catalog #349-F4), human VEGF R1 (Catalog #321-FL), human VEGF R2 (Catalog #357-KD) or human Tie-2 (Catalog #313-TI) were added to 20 μg NS0-hVEGF R3 cell lysate and analyzed using this DuoSet IC ELISA. Competition was observed only with recombinant human VEGF R3.Kit Contents for Human Phospho-VEGFR3/Flt-4 DuoSet IC ELISA

Background: VEGFR3/Flt-4
VEGF R1 (Flt-1), VEGF R2 (KDR/Flk-1), and VEGF R3 (Flt-4) belong to the class III subfamily of receptor tyrosine kinases (RTKs). All three receptors contain seven immunoglobulin-like repeats in their extracellular domain and kinase insert domains in their intracellular region. They are best known for regulating VEGF family-mediated vasculogenesis, angiogenesis, and lymphangiogenesis. They are also mediators of neurotrophic activity and regulators of hematopoietic development. VEGF R2 is thought to be the primary inducer of VEGF-mediated blood vessel growth, while VEGF R3 plays a significant role in VEGF-C and VEGF-D-mediated lymphangiogenesis.
