The M.Ab.F11 monoclonal antibody specifically binds to CD321 which is also known as JAM-1 (Junctional adhesion molecule 1), Junctional adhesion molecule A (JAM-A), and F11 Receptor (F11R). CD321 is a 32-35 kDa type I transmembrane glycoprotein that includes two extracellular immunoglobulin-like domains. CD321 is expressed on platelets, leucocytes, red blood cells, endothelial cells, epithelial cells, and various cell lines. CD321 functions as an adhesion receptor molecule on platelets. It also supports the tight junction formation between endothelial cells, where it may regulate the transendothelial migration of leucocytes, and epithelial cells. M.Ab.F11 is a stimulatory antibody that can induce morphological changes, granule secretion, and aggregation in human platelets.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
