Recombinant Mouse CD31 (C-6His, HEK293) is a mouse-derived recombinant protein expressed in HEK293 human cells and tagged with a C-terminal 6×His tag. This protein corresponds to platelet endothelial cell adhesion molecule-1 (PECAM-1, also known as CD31), a type I transmembrane glycoprotein belonging to the immunoglobulin superfamily. It is predominantly expressed in cells of the circulatory system and plays a key role in regulating leukocyte transendothelial migration. The extracellular domain contains multiple glycosylation sites and immunoglobulin-like domains, while the intracellular domain is involved in signal transduction.

Synonyms: Recombinant Mouse CD31 (C-6His, HEK293); Platelet endothelial cell adhesion molecule; PECAM-1

Biological Activity

Description
Platelet endothelial cell adhesion molecule (PECAM-1, CD31) is a type I transmembrane glycoprotein adhesion molecule in the immunoglobulin superfamily. PECAM-1 is concentrated at cell junctions and is required for transendothelial migration (TEM). The extracellular domain (ECD) of PECAM-1 has ten potential N-linked glycosylation sites and six C2-type Ig-like domains, the first of which is critical for adhesion and extravasation. The cytoplasmic domain contains immunoregulatory tyrosine-based inhibitory and switch motifs (ITIM, ITSM) that mediate both inhibition and activation via phosphotyrosine-mediated engagement of SH2-containing signaling molecules. Expression is restricted to cells involved in circulation, especially endothelial cells, platelets, monocytes, neutrophils and lymphocyte subsets. PECAM-1 participates with other adhesion molecules in some functions, but is the critical molecule for TEM. Homotypic PECAM-1 adhesion in trans, combined with cycling of PECAM-1 to and from surface-connected endothelial cell vesicles, leads leukocytes across endothelial tight junctions.
Protein Species Mouse
Expression System Human Cells
Tag C-6His
Protein Expression Interval Glu18-Lys590
Protein ID Q08481
Endotoxin < 1 EU/µg as determined by LAL test.
Characteristics Lyophilized powder
Formulation Description Lyophilized from a 0.2 μm filtered solution of PBS, 5mM EDTA, pH7.4.
Reconstitution Method Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
For long-term storage, it is recommended to further dilute the product with a solution containing carrier proteins (e.g., 0.1% BSA, 10% FBS, or 5% HSA). For serum-free cultures or in vivo animal experiments where BSA, FBS, or HSA cannot be present in the cytokine preparation, trehalose may be used as an alternative carrier. Aliquots should be stored frozen at -20°C to -80°C.
Note: Low-adsorption tubes are recommended for aliquot storage, and repeated freeze-thaw cycles should be avoided. The dilution concentration for aliquoting should not be lower than 10 μg/mL, and the aliquot volume should be no less than 10 μL.
Aliquoted protein remains stable for up to 3 months when stored at ≤ -20°C.
