Most studies on the adhesion molecules are performed by multiwell plates and this approach consumes considerable quantities of samples. Most of the studied samples are proteins purified from tissues. Thus, they could be expensive and hard to obtain. They can also be limited in quantity, especially when the source of the samples is human. 	cell adhesion microarray assay	http://cellassay.creative-bioarray.com/services/cell-adhesion-microarray-service.htm
