Product Overview

Tag	N/A
Host Species	Human
Accession	NP_620411.2
Synonym	W117m
Background	Endothelial cell-selective adhesion molecule (ESAM) is a member of JAM family of immunoglobulin superfamily and consists of one V-type and one C2-type immunoglobulin domain, as well as a hydrophobic signal sequence, a single transmembrane region, and a cytoplasmic domain. It is specifically expressed at endothelial tight junctions and on activated platelets. ESAM at endothelial tight junctions participates in the migration of neutrophils through the vessel wall, possibly by influencing endothelial cell contacts. The adaptor protein membrane-associated guanylate kinase MAGI-1 has been identified as an intracellular binding partner of ESAM. Previous studies have indicated that ESAM regulates angiogenesis in the primary tumor growth and endothelial permeability. It suggest that ESAM has a redundant functional role in physiological angiogenesis but serves a unique and essential role in pathological angiogenic processes such as tumor growth.
Description	The mature form of human ESAM (NP_620411.2) extracellular domain (Met 1-Ala 248) with five amino acids (DDDDK) at the C-terminus was expressed and purified.
Source	HEK293
Predicted N Terminal	Gln 30
AA Sequence	Met 1-Ala 248
Molecular Weight	The recombinant human ESAM consists of 225 a.a. and predicts a molecular mass of 24.5 kDa. By SDS-PAGE under reducing conditions, the apparent molecular mass of rh ESAM is approximately 40-45 kDa due to the glycosylation.
Purity	>92% as determined by SDS-PAGE
Endotoxin	< 1.0 EU per μg of the protein as determined by the LAL method
Bioactivity	Please contact us for detailed information
Formulation	Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5.
Stability	The recombinant proteins are stable for up to 1 year from date of receipt at -70°C.
Usage	For Research Use Only
Storage	Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
