Recombinant Human CD31 antigen expressed in HEK293 cells comprises the extracellular domain of CD31, otherwise known as PECAM-1, a member of the Ig-related superfamily of adhesion molecules, expressed by endothelial cells, platelets, granulocytes and some lymphocytes, and plays a key role as a mediator of leucocyte-endothelial cell adhesion and leucocyte transendothelial migration, during inflammatory responses. CD31 has been linked with various inflammatory disorders including atherosclerosis, rheumatoid arthritis (RA) and multiple sclerosis (MS).

Carrier Free
Determined by its ability to support the adhesion of activated Jurkat cells. The expected ED50 for this effect is 1.0 -1.5 μg/ml.
>97% by SDS PAGE and HPLC analysis
Approx. Protein Concentrations
0.1 mg/ml after reconstitution
Protein Molecular Weight
Recombinant protein comprising the extracellular domain of CD31 (572 amino acid residues). Monomeric glycosylated CD31 migrates at approximately 80-95 kDa by SDS PAGE, under reducing conditions.
Endotoxin Level
< 1.0 EU/ug

Storage Information

Prior to reconstitution store at +4oC.
After reconstitution store at -20oC.
