GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥95%(SDS-PAGE)See COA

Overview
The CD31 adhesion molecule, also known as PECAM-1, 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. CD31 binds to itself homotypically, and also to the leukocyte integrin alpha v beta 3 heterotypically. CD31 is required for the transendothelial migration of leukocytes through intercellular junctions of vascular endothelial cells. CD31 has been found in human plasma, and the presence of this circulating isoform is suggested to modulate the transendothelial migration of leukocytes. Post-translational: Phosphorylated on Ser and Tyr residues after cellular activation by src kinases (PubMed:18710921, PubMed:19342684, PubMed:21464369, PubMed:9298995). Upon activation, phosphorylated on Ser-729 which probably initiates the dissociation of the membrane-interaction segment (residues 709-729) from the cell membrane allowing the sequential phosphorylation of Tyr-713 and Tyr-690 (PubMed:21464369). Constitutively phosphorylated on Ser-734 in resting platelets (PubMed:21464369). Phosphorylated on tyrosine residues by FER and FES in response to FCER1 activation (By similarity). In endothelial cells Fyn mediates mechanical-force (stretch or pull) induced tyrosine phosphorylation (PubMed:18710921). Palmitoylation by ZDHHC21 is necessary for cell surface expression in endothelial cells and enrichment in membrane rafts.
