Human Fc Receptor Blocking Solution

This buffer contains specialized human IgG in PBS containing 0.09% sodium azide. It is not recommended to be used for staining human IgG. Handle as biohazard agent.

Human Fc receptors (FcRs) are expressed on a variety of cells, such as monocytes, granulocytes, B cells and dendritic cells. The cells with FcR expression sometimes give false positive or false negative results of immunofluorescent staining due to the FcRs-mediated Ig Fc binding. Human Fc Receptor Blocking Solution is specially formulated for blocking the FcR-involved unwanted staining without interfering with antibody-mediated specific staining of human cells.
