PECAM-1, Recombinant, Human (Platelet endothelial cell adhesion molecule, CD31 antigen, EndoCAM)

PECAM is transmembrane glycoprotein that belongs to the Ig-related superfamily of adhesion molecules.It is highly expressed at endothelial cell junctions, and also expressed in platelets and in most leukocyte sub-types. The primary function of PECAM-1 is the mediation of leukocyte-endothelial cell adhesion and signal transduction.PECAM-1 has been implicated in the pathogenesis of various inflammation related disorders, including thrombosis, multiple sclerosis (MS), and rheumatoid arthritis. The human PECAM-1 gene codes for a 738 amino acid transmembrane glycoprotein containing a 118 amino acid cytoplasmic domain, a 19 amino acid transmembrane domain, and a 574 amino acid extracellular domain. Recombinant human PECAM-1 is a 572 amino acid glycoprotein comprising the extracellular domain of PECAM-1.Monomeric glycosylated PECAM-1 migrates at an apparent molecular weight of approximately 80.0-95.0kD by SDS-PAGE analysis under reducing conditions\n\nBiological Activity:\nDetermined by its ability to support the adhesion of activated Jurkat cells. The expected ED50 for this effect is 1.0-1.5ug/ml.\n\nAA Sequence:\nENSFTINSV DMKSLPDWTV QNGKNLTLQC FADVSTTSHV KPQHQMLFYK DDVLFYNISS MKSTESYFIP EVRIYDSGTY KCTVIVNNKE KTTAEYQLLV EGVPSPRVTL DKKEAIQGGI VRVNCSVPEE KAPIHFTIEK LELNEKMVKL KREKNSRDQN FVILEFPVEE QDRVLSFRCQ ARIISGIHMQ TSESTKSELV TVTESFSTPK FHISPTGMIM EGAQLHIKCT IQVTHLAQEF PEIIIQKDKA IVAHNRHGNK AVYSVMAMVE HSGNYTCKVE SSRISKVSSI VVNITELFSK PELESSFTHL DQGERLNLSC SIPGAPPANF TIQKEDTIVS QTQDFTKIAS KSDSGTYICT AGIDKVVKKS NTVQIVVCEM LSQPRISYDA QFEVIKGQTI EVRCESISGT LPISYQLLKT SKVLENSTKN SNDPAVFKDN PTEDVEYQCV ADNCHSHAKM LSEVLRVKVI APVDEVQISI LSSKVVESGE DIVLQCAVNE GSGPITYKFY REKEGKPFYQ MTSNATQAFW TKQKASKEQE GEYYCTAFNR ANHASSVPRS KILTVRVILA PWK\n\nQuality Control:\nVerified by N-terminal and Mass Spectrometry analyses (when applicable).\n\nEndotoxin:\n<0.1ng/ug of protein (<1EU/ug).\n\nProtein Content:\nVerified by UV Spectroscopy and/or SDS-PAGE gel.\n\nStorage and Stability:\nStore lyophilized products at -20 degrees C. For reconstituted solutions of most products, we recommend short-term storage at 4 degrees C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20 degrees C. Additional freeze/thaw cycles may cause some denaturation of the protein.
