Human Phospho-VEGFR1/Flt-1 DuoSet IC ELISA Summary

Assay Type
Solid Phase Sandwich ELISA
Format
96-well strip plate
Sample Volume Required
Cell lysates (100 µL)
Sufficient Materials
Kits available for two, five, or fifteen 96-well plates*
Specificity

* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure tyrosine-phosphorylated human VEGF R1 / Flt-1 in cell lysates. An immobilized capture antibody specific for VEGF R1 / Flt-1 binds both phosphorylated and unphosphorylated VEGF R1 / Flt-1. After washing away unbound material, a biotinylated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

Background: VEGFR1/Flt-1

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.
