Angiogenesis Assay Kit ab204726 provides a quick and robust method to measure the ability of endothelial cells to from three-dimensional tube-like structures in vitro in less than 18 hours. This tube formation assay provides a simple, easy to perform, qualitative tool for assessing angiogenesis.
Angiogenesis assay protocol summary:
- add extracellular matrix solution to empty culture plate and incubate for 1 hr at 37ºC to allow the solution to form a gel
- plate cells onto the gel and add experimental treatment
- incubate cells for 4-18 hrs to allow tube formation
- remove incubation medium and wash cells / gel
- add staining dye and incubate for 30 min
- examine tube formation using light and fluorescence microscopy (green filter)
This product is manufactured by BioVision, an Abcam company and was previously called K905 Angiogenesis (Tube Formation) Assay. K905-50 is the same size as the 50 test size of ab204726.
Angiogenesis is a physiological process that occurs during wound healing and normal development which involves the growth of new blood vessels from pre-existing vessels. These blood vessels form highly branched, tree-like tubular networks that ensure efficient and simultaneous transport of gases, liquids, nutrients, signaling molecules, and circulating cells between tissues and organs. Angiogenesis is complex and highly regulated, with tight coordination of cell proliferation, differentiation, migration, matrix adhesion, and cell-to-cell signaling. Angiogenesis is regulated by several factors, most importantly growth factors such as vascular endothelial growth factors (VEGFs) and platelet-derived growth factors (PDGFs).
