Siglec-8, also known as SAF, is an approximately 75 kDa transmembrane glycoprotein in the Siglec family of sialic acid-binding immune regulatory molecules. Mature human Siglec-8 co nsists of a 347 amino acid (aa) extracellular domain (ECD) with three Ig-like domains.Putative adhesion molecule that mediates sialic-acid dependent binding to red blood cells. Preferentially binds to alpha-2,3-linked sialic acid. Also binds to alpha-2,6-linked sialic acid. Specifications Synonyms CDw329; MGC59785; SAF2; SAF2SAF-2; Siglec-8; SIGLEC8L; SIGLEC8 Uniprot No. Q9NYZ4 Source Recombinant Biotinylated Human Siglec-8 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Met17-Ala363. Molecular Weight The protein has a predicted MW of 40.7 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water. Storage The products are shipped with ice pack and can be stored at -20℃ for 1 year. 2-7 days, 2 to 8 °C under sterile conditions after reconstitution.3 -6 months, -20 to -80°C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. Note 1. For your safety and health, please wear lab coats and disposable gloves for operation. 2. For research use only! Product Data Show more
