WebFc regions of many antibodies readily bind to the Fc-receptors at different levels. Most commercially available antibodies contain Fc segments. To eliminate this problem, one can use an Fc blocking reagent, which contains a recombinant protein derived from immunoglobulin that will bind to the Fc-receptors and minimize the non-specific binding.

There are several different types of Fc receptors (abbreviated FcR), which are classified based on the type of antibody that they recognize. The Latin letter used to identify a type of antibody is converted into the corresponding Greek letter, which is placed after the 'Fc' part of the name.
