V2a Kit

V2a Kit™ - Vasculogenesis to Angiogenesis


The V2a Kit contains all of the cells and reagents necessary to successfully complete a 24 well angiogenesis assay and includes a cryogenically preserved ampoule of matched cells, 24 well tissue culture plate, medium, supplements, control compounds and all staining reagents.

The V2a Kit allows analysis of all aspects of the angiogenic pathway including; cell activation, cell proliferation, migration, elongation and anastomosis with complete flexibility of experimental timing. It is designed so that test compounds, conditioned media or tissue explants can be added to the culture at any time from the onset of vasculogenesis continuing through to advanced angiogenesis.

Control wells that receive no treatment other than medium changes form extensive networks of branching tubules over a period of one to two weeks. This allows both angiogenic inhibitors and angiogenic stimulators to be assessed. The necessary medium changes are included in the kit.

Positive and negative control compounds are included in the V2a Kit which consist of validated concentrated stock solutions of VEGF (2ug/ml, positive control) and Suramin (1mM, negative control) ready to add to medium.
