Clone REAL507 is an antibody fragment derived from the full CD146 (LSEC) antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAdye_lease Complex to bind markers with high avidity.

Clone REAL507 recognizes the mouse CD146 antigen, which is expressed on mouse endothelial cells, including liver sinusoidal endothelial cells (LSECs), smooth muscle cells, and the basal membrane. LSECs are microvascular endothelial cells lining the hepatic sinusoidal wall. Their strategic positioning favors a tight interaction with lymphocytes migrating through the liver. They possess a high capacity for antigen uptake and processing. However, in contrast to professional antigen-presenting cells, e.g. dendritic cells, they express only low levels of costimulatory molecules.

For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675).
