Background

Many cell types such as monocytes, granulocytes, B cells and dendritic cells express Fc receptors (FcRs) on their surfaces (See Table 1). FcR-mediated IgFc binding can negatively affect the results of immunofluorescent staining by reducing the separation of negative and positive cell populations during flow cytometric analysis.2 In immunohistochemistry staining, the Fc interactions with FcR can be the cause of high fluorescent background levels. The advantage of using a Fc blocking reagent which has been investigated and shown to be effective in blocking Fc-FcR interactions is higher resolution and therefore, more accurate results.2 Isotype controls were widely accepted previously as a necessary and useful part of flow cytometry experiments. However, isotype controls have lost scientific consensus for use in flow cytometry and have become less reliable due to their inability to mitigate every concern associated with undesirable antibody behavior.2,3 Fc Blocking reagents have also shown higher efficacy in background reduction compared to serum because of the lot to lot consistency.2 RealStain, Leino's purified Fc Block solution was carefully engineered with the optimal ratio of non-specific murine IgG isotype control molecules to efficiently and completely block human Fc receptors during cell staining thus helping prevent false negative or false positive results. RealStain Fc block solution can be used to avoid undesired non-specific staining of primary antibodies. Human RealStain Fc Block IS NOT compatible with using Anti-murine secondary conjugates because it contains murine isotype control antibodies
