VEGFR-1 Protein, Human (Biotinylated, HEK293, His-Avi)

Cat. No.: HY-P78230
Data Sheet Handling Instructions Technical Support

The VEGFR-1 protein is a tyrosine protein kinase that acts as a cell surface receptor for VEGFA, VEGFB, and PGF. It plays a crucial role in embryonic vasculature development, regulation of angiogenesis, cell survival, migration, macrophage function, chemotaxis, and cancer cell invasion. VEGFR-1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived VEGFR-1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Description

The VEGFR-1 protein is a tyrosine protein kinase that acts as a cell surface receptor for VEGFA, VEGFB, and PGF. It plays a crucial role in embryonic vasculature development, regulation of angiogenesis, cell survival, migration, macrophage function, chemotaxis, and cancer cell invasion. VEGFR-1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived VEGFR-1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Background

VEGFR-1 Protein is a tyrosine-protein kinase that serves as a cell-surface receptor for VEGFA, VEGFB, and PGF. It plays a crucial role in various biological processes, including embryonic vasculature development, angiogenesis regulation, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. Additionally, VEGFR-1 acts as a positive regulator of postnatal retinal hyaloid vessel regression and may function as a negative regulator of embryonic angiogenesis by inhibiting excessive endothelial cell proliferation. In adulthood, it promotes endothelial cell proliferation, survival, and angiogenesis, although its proliferative effects appear to be cell-type specific. VEGFR-1 has a high affinity for VEGFA and acts as a negative regulator of its signaling by limiting the availability of free VEGFA and preventing its binding to KDR. It modulates KDR signaling by forming heterodimers with KDR. Ligand binding to VEGFR-1 activates several signaling cascades, including PLCG, MAPK1/ERK2, MAPK3/ERK1, AKT1, and PI3K pathways. VEGFR-1 also phosphorylates SRC, YES1, CBL, AKT1, PTK2/FAK1, and PLCG.

Biological Activity

Measured by its binding ability in a functional ELISA. When immobilized Human VEGF165 at 1 μg/ml (100μl/Well), can bind Biotinylated Human VEGF R1 His and the EC50 is 25-30 ng/mL.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
