For short term storage S100 Beta Chain (Western Blot Control) 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 S100 Beta Chain (Western Blot Control) 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.
Western Blot can be performed on tissues and cell extracts to determine the proteins present in your sample after PAGE electrophoresis and transfer on PVDF or Nitrocellulose. PVDF is more advised. The best detection method is using enhanced chemiluminescence or ECL.
Isotype or positive controls by peptides, antibodies and deactivated samples.
