IHControls® are grouped together so that a single control will be useful for multiple different primary antibodies, often to different protein biomarkers. The groups are organized by subject area. For example, HER2, ER, and PR are grouped together as a breast cancer panel. In addition to the different analyte specificities, there are also multiple different concentrations of each that are often available. This ensures that your lab uses the correct concentration that is most sensitive. Our studies have demonstrated that controls with too high a concentration are insensitive (1). There is an approximately ten-fold difference in antigen concentration between each level. We recommend using the lowest antigen concentration that provides an easily detectable stain. That concentration may not be the same for HER-2, ER, and PR and should be determined in your lab.
