We offer antibodies against the most common loading and expression control proteins. Loading control antibodies are helpful for assessing western blotting efficiencies and comparing the amounts of protein loaded in each well across a gel. These controls help determine whether sample-to-sample expression level differences are due to actual protein levels in a given cell lysate or from loading variances. Loading control antibodies can also be used as complementary antibody stains in immunofluorescence studies with proteins of interest. Loading control antibodies are available in unconjugated form, or conjugated to biotin, HRP, or Invitrogen Alexa Fluor dyes.
Loading control antibodies are used to assess levels of protein expression and verify the efficiency and quality protein transfer for western blot analysis. Use our checklist to help you choose the appropriate loading control antibody. Review the table to help identify the right-sized loading control for your sample type.
