• Buffer/Preservatives: Lyophilized from a 0.2 µm filtered PBS, pH 7.4, with 0.02 % Tween-20
• Alternative names: LT-alpha, Tumor necrosis factor ligand superfamily
• Note: For research use only
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
• Expiration Date: 6 months from date of receipt.
