ab_Loading_Controls_230
We offer antibodies against the most common loading and expression control proteins. Loading control antibodies are helpful for assessing western blotting efficiency, and they are used to compare the amount of protein loaded in each well across the gel. These controls help determine whether sample-to-sample expression level differences of the protein of interest are due to actual protein levels in a given cell lysate or from loading variance in sample preparations. Loading control antibodies can also be used as a complementary antibody stain in immunofluorescence studies with your protein of interest. We offer loading control antibodies against GAPDH, beta actin, and beta tubulin conjugated to biotin, HRP, and assorted fluorescent dyes.
