Learn about selecting an appropriate negative control antibody, one which lacks target specificity but otherwise matches the immunoglobulin class and type of the primary antibody used in an immunoassay application.
Select an antibody against a common loading or expression control protein. These are helpful in western blotting, where they enable comparison of the amount of protein loaded in each well across a gel.
