Galectin-9 is a secreted carbohydrate-binding protein with two lectin domains connected by a linker region.Galectins are a family of proteins defined by their binding specificity for β-galactoside sugars, such as N-acetyllactosamine , which can be bound to proteins by either N-linked or O-linked glycosylation. Specifications Synonyms Ecalectin; GAL9; gal-9; Galectin9; Galectin-9; HUAT; LGALS9; LGALS9A; MGC117375; MGC125973; MGC125974 Uniprot No. O00182-2 Source Recombinant Human Galectin 9/LGALS9 Protein is expressed from HEK293 with His tag at the N-terminal. It contains Ala2-Thr323 Molecular Weight The protein has a predicted MW of 36.9 kDa. Due to glycosylation, the protein migrates to 60-68 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 0.22 μm 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 100 μg/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 months, -20 °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
