CD31/PECAM-1 Protein, Human (HEK293, His)

CD31/PECAM-1 Protein is a cell-cell adhesion protein that is found on the surface of platelets, monocytes, neutrophils, and some types of T-cells, and makes up a large portion of endothelial cell intercellular junctions^[1][2]. CD31/PECAM-1 Protein, Human (HEK293, His) is the recombinant human-derived CD31/PECAM-1 protein, expressed by HEK293 , with C-6*His labeled tag.

CD31/PECAM-1 Protein is expressed in large amounts on endothelial cells at intercellular junctions and on T cell subsets, and to a lesser extent on platelets and most other leukocytes such as monocytes and neutrophils^[1][2]. CD31/PECAM-1 Protein binds to itself homotypically, and also to the leukocyte integrin alpha v beta 3 heterotypically^[3]. CD31/PECAM-1 Protein is required for the transendothelial migration of leukocytes through intercellular junctions of vascular endothelial cells^[4].

75-110 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, 1 mM EDTA, pH 7.4 .

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
