PECAM-1/CD31 was present mainly on luminal surfaces and at the junctions between endothelial cells. PMID: 10950884. CD31 is distributed over the entire endothelial cell surface, exclusive of specialized junctions, and in VVOs, but is not equally accessible to different antibodies in all locations.latelet endothelial cell adhesion molecule-1 (PECAM-1/CD31) acts as a regulator of B-cell development, B-cell antigen receptor (BCR)-mediated activation, and autoimmune disease.
Zinc is currently at .863 per lb which is .053 per ounce.
Minimum cost: $8,000 - $10,700 for 1,200 square feet. Maximum cost: $13,400 - $15,000 for 1,200 square feet. Cost per square footage: $10 - $20 per square foot. Zinc may actually end up being cheaper and more cost effective than most metals when comparing the costs of installation and upkeep to that of copper and lead. Metal theft is more unlikely with zinc roofs as well.
