Description: CD321 (F11R, JAM-1, JAM-A) is a cell-surface adhesion molecule belonging to the Ig superfamily of receptors. CD321 is a 32-41 kD glycoprotein, possessing two extracellular Ig-like domains, a transmembrane region, and a short cytosolic tail. The protein assembles at the membrane as a homodimer, and can associate laterally with other membrane proteins including integrins. CD321 is expressed on a variety of cell types, including leukocytes, platelets, erythrocytes, epithelial and endothelial cells, and plays a role in mediating cell-cell contact. CD321 can be found in close proximity to several components of epithelial tight junctions, including ZO-1 and occludin. CD321 is also involved in reovirus entry into cells. Applications Reported: This WK9 antibody has been reported for use in flow cytometric analysis and immunoprecipitation. The WK9 antibody has also been found useful for immunoblotting, recognizing a protein of approximately 38 kD under reducing and non-reducing conditions. Applications Tested: This WK9 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered. Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. The protein encoded by this immunoglobulin superfamily gene member is an important regulator of tight junction assembly in epithelia. In addition, the encoded protein can act as (1) a receptor for reovirus, (2) a ligand for the integrin LFA1, involved in leukocyte transmigration, and (3) a platelet receptor. Multiple alternatively spliced variants, encoding the same protein, have been identified.
