As mentioned in the datasheet, THE™ PEG Antibody, mAb, mouse should be stored in its lyophilized form until use. It remains stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C or for up to 12 months at -20°C or below. Avoid repeated freeze-thaw cycles.
Reconstitute the lyophilized product with deionized water (or equivalent) to make an antibody concentration of 0.5 mg/ml. For long-term storage, it is recommended to add glycerol to a final concentration of 50% (v/v) in the reconstituted antibody solution.
