|PECAM1, CD31, PECAM-1|
|A DNA sequence encoding the extracellular domain (Met 1-Lys 601) of human CD31 (EAW94208.1) was expressed with the fused Fc region of human IgG1 at the C-terminus.|
|In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.|
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|> 95 % as determined by SDS-PAGE|
|Measured by its ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When 8 × 10E4 cells/well are added to sCD31-Fc coated plates (1.25μg/mL, 100μL/well) in the presence of 20ng/mL PMA, approximately 20-45% will adhere after 30 minutes at 37℃.|
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant human CD31/Fc is a disulfide-linked homodimer.The reduced monomer consists of 812 amino acids and predicts a molecular mass of 91.2 kDa. As a result of glycosylation, the rhCD31/Fc monomer migrates as approximately 130-140 kDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile 100mM Glycine, 10mM NaCl, 50mM Tris, pH 7.5|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
The Cluster of Differentiation 31 (CD31) adhesion molecule, also known as platelet-endothelial cell adhesion molecule-1 (PECAM-1), is the only known member of the CAM family on platelets. CD31 protein is a 130-kDa transmembrane glycoprotein expressed by endothelial cells, platelets, monocytes, neutrophils, and certain T cell subsets. CD31 protein is also expressed in certain tumors, including epithelioid hemangioendothelioma, other vascular tumors, and histiocytic malignancies. CD31 plays a key role in removing aged neutrophils and tissue regeneration. CD31 protein mediates the homotypic or heterotypic cell adhesion by binding to itself or the leukocyte integrin αvβ3, and thus plays a role in neutrophil recruitment in inflammatory responses, transendothelial migration of leukocytes, as well as in cardiovascular development.
