Description

VEGF165 Protein, Human (HEK293) is a Vascular Endothelial Growth Factor A (VEGF-A) isoform. VEGF is a heparin-binding growth factor specific for vascular endothelial cells that is able to induce angiogenesis.

Background

Vascular Endothelial Growth Factor (VEGF) has multiple isoforms, created by alternative splicing or proteolytic cleavage, and characterized by different receptor-binding and matrix-binding properties. These isoforms are known to give rise to a spectrum of angiogenesis patterns marked by differences in branching, which has functional implications for tissues. VEGF-A is a key member of the VEGF family of cytokines, along with VEGF-B, -C, -D, and PlGF. VEGF-A mediates angiogenesis, the expansion of an existing vascular bed by sprouting of new blood vessels. The vegfa gene is translated into a number of splice isoforms, the most notable in humans being VEGF121, VEGF165, and VEGF189[1].

Biological Activity

Measured in a cell proliferation assay using HUVEC human umbilical vein endothelial cells. The ED50 this effect is ≤5 ng/mL.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS or 20mM Citrate, 8% Sucrose, 4% Mannitol, 0.05% Tween 80, pH4.0 or 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. 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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

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)
× = ×

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
