Product Properties Alternative Names ANK-T-B-antigen, NTB-A, CD352, SLAMF6, KALI, Ly108, NK-T-B-antigen, KALIb, SF2000 Species Mouse Expression Sequence Glu31-Asn239 Accession Q9ET39-1 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 24.03 kDa. Due to glycosylation, the protein migrates to 40-55 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Reconstitution Method Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 to -15°C. The shelf life is 1 year from the date of receipt. After reconstitution, store at -85 to -65°C under sterile conditions for up to 3 months.
