• Form: Lyophilized powder
• Buffer: Lyophilized from a 0.2 μm filtered solution containing PBS, 5% mannitoland 0.01% Tween 80, pH 7.4
• Reconstitution: 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.
