Product Specs
Form
Lyophilized powder. We will preferentially ship the available format. If you have specific format requirements, please note them when ordering.
Lead Time
Delivery times vary by purchasing method and location. Consult local distributors for specific delivery times. All proteins are shipped with normal blue ice packs by default. For dry ice shipping, contact us in advance; extra fees apply.
Notes
Avoid repeated freezing and thawing. Store working aliquots at 4°C for up to one week.
Reconstitution
Briefly centrifuge the vial before opening. Reconstitute protein in sterile deionized water to 0.1-1.0 mg/mL. Add 5-50% glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final glycerol concentration is 50%.
Shelf Life
Shelf life depends on storage conditions, buffer ingredients, storage temperature, and protein stability. Liquid form: 6 months at -20°C/-80°C. Lyophilized form: 12 months at -20°C/-80°C.
Storage Condition
Store at -20°C/-80°C upon receipt. Aliquot for multiple uses. Avoid repeated freeze-thaw cycles.
