Catalog No: OONB00068

Product Info

• Product Format: Lyophilized 0.05M HEPES, 0.15M NaCl and 5% sucrose. Bubbly/glassy residue due to lyophilization in 5% sucrose to increase product stability.
  Inactivation method: Formaldehyde. No cell rounding in the sensitive verocytotoxicity assay at 2 ug/mL compared to the active toxin lethal dose of 0.2 ng/ml.
• Reconstitution and Storage: Store at 2-8°C for up to 1 year after date of receipt. Store reconstituted liquid at 2-8°C for up to one month. Reconstituted liquid can be frozen at -80°C to extend stability to 1 year; however every freeze/thaw cycle will cause increased aggregation. Avoid multiple freeze/thaw cycles and multiple temperature fluctuations. Swirl or pipette gently to mix. Vortexing promotes aggregation.
