Reconstitute with 0.5 ml distilled water
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. RayBiotech recommends that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended.
N.B. For functional studies do not add sodium azide
Prior to reconstitution store at +4° C. Following reconstitution store at -20° C.
