Loading Control Antibodies

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.
