Product name: CD144 (VE-cadherin) Monoclonal Antibody (16B1), Alexa Fluor™ 488, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: The 16B1 antibody reacts with human CD144, also known as VE-cadherin and cadherin-5. The cadherin family of receptors, which are calcium-dependent adhesion molecules, is known to be involved in homophilic cell interactions. VE-cadherin, which is 140 kDa, is localized at the intercellular boundaries of endothelial cells in blood and lymphatic vessels in several tissues. It is thought to play a role in vascular permeability and remodeling.
