Vascular endothelial growth factor (VEGF) is a signalling protein that plays a crucial role in angiogenesis, the formation of new blood vessels from pre-existing ones. It is produced by many different cell types, including endothelial cells, macrophages, and tumour cells, and is a key regulator of blood vessel growth and maintenance. The physiological functions of VEGF include promoting the proliferation and migration of endothelial cells, as well as increasing vascular permeability. VEGF also stimulates the production of nitric oxide, a potent vasodilator, which helps to increase blood flow to tissues. In addition to its role in normal tissue growth and repair, VEGF is also involved in pathological processes such as tumour angiogenesis and ocular neovascularization. VEGF has been found to be overexpressed in many types of cancer, including breast, lung, colorectal, and kidney cancer, among others. Its overexpression has been associated with increased tumour growth, invasion, and metastasis, as well as poor prognosis and resistance to chemotherapy and radiotherapy.

The biotin labelling of this antibody ensures strong and stable interaction with avidin or streptavidin, making it suitable for a wide range of downstream applications.

PtX™ | Plant-Based Expression

The biotechnology behind the development and manufacture of this product, transient plant-based expression, effectively turns Nicotiana benthamiana plants into single-use, biodegradable bioreactors. Infiltrating this plant species with Agrobacterium tumefaciens cells, transformed with our proprietary plant expression vectors, allows rapid production of a wide variety of recombinant proteins. Plants are harvested and proteins extracted by various stages of filtration, clarification, purification, and polishing – resulting in a highly functional final product.
