VEGF Proliferation Assay
1. Prior to use in this assay, maintain HUVE cells in F-12K medium supplemented with 10% (v/v) FBS, 1% penicillin-streptomycin-glutamine, 0.1 mg/ml heparin and 0.05 mg/ml endothelial cell growth supplement (ECGS).
2. For assay of VEGF, subculture HUVE cells into a 96-well plate at a density of 4,000 cells per well in the growth medium over night.
3. Add VEGF to a final concentration range of 0.2, 0.4, 0.8, 1.6, 3.2, 6.2, 12.5, 25 and 50ng/ml. Add VEGF diluent to one set of wells as the negative control.
4. Four days later, add 20ul of Promega Substrate Cell Titer 96 Aqueous One Solution Reagent to each well.
5. Incubate at 37C for 2 hrs and read at OD 490nm.

품질
Routinely evaluated in a 5-day growth assay using human umbilical vein endothelial cells
Cell Proliferation Assay: The biological activity of this lot of VEGF was determined by its mitogenic activity on human umbilical vein endothelial cells (HUVEC) with an ED50 of about 1.0 ng/mL. Results may vary depending on the cell line used. VEGF will also stimulate endothelial cells from other species.

물리적 형태
10 µg VEGF protein was lyophilized from buffer containing 25mM HEPES and 150mM NaCl, pH 7.0. Carrier free.

Sterilized through a 0.2 micron membrane filter
저장 및 안정성
The lyophilized powder is stable for a few weeks at room temperature, but best stored at -20°C for up to one year from date of receipt. After a quick spin, reconstitute with sterile water or 25mM HEPES and 150mM NaCl, pH 7.0. Reconstituted material can be stored at 2°-8°C for one week, but undiluted aliquots at -20°C are recommended. Avoid repeated freeze/thaw cycles.
This product is acid stable. Dilute in either 0.1% TFA or 4mM HCl, containing 25ug BSA per ug VEGF to maintain stability. Reducing reagents (such as dithiothrietol or 2-mercaptoethanol) inhibit VEGF activity.

Mutations in the RB1 locus leading to a loss of functional Rb protein cause intraocular tumors, which uniquely affect children worldwide. These tumors demonstrate rapid proliferation, which has recently been shown to be associated with an altered metabolic signature. We

This protocol describes how to form a 3D cell culture with explicit, endothelialized microvessels. The approach leads to fully enclosed, perfusable vessels in a bioremodelable hydrogel (type I collagen). The protocol uses microfabrication to enable user-defined geometries of the vascular

Cancer progression is supported by the cross-talk between tumor cells and the surrounding stroma. In this context, senescent cells in the tumor microenvironment contribute to the development of a pro-inflammatory milieu and the acquisition of aggressive traits by cancer cells.
