For short term storage Control IgG Protein may be kep at +4 deg. C. For long term storage keep the aliquoted vials frozen at -20 degrees Celsius.
Due to handling and transportation, small amounts of the Control IgG Protein may get caught on the walls or seal of the vials. Prior to use briefly rund the vial(s) through a centrifuge to collect all of the content on the bottom. Avoid freezing and thawing the vials numerous times as such cycles may denaturate the peptide chains and influence the item's performance.
Isotype or positive controls by peptides, antibodies and deactivated samples.
