Presentation
Lyophilized from sterile Tris, pH 8.0, NaCl
Reconstitution
Reconstitute in distilled water to 0.1 mg/ml.
Storage
The lyophilized protein is stable for up to 1 year at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2°C to 8°C for 1 month, or at -20°C for 6 months, with a carrier protein without detectable loss of activity. Avoid freeze/thaw cycles.
