- Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
- Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg mL. Stock solutions should be apportio
- Storage This lyophilized preparation is stable at 2-8 ˚C, but should be kept at -20 ˚C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 ˚C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 ˚C to -70 ˚C. Avoid repeated freeze thaw cycles.
