|Active Blocking Reagents
|Designed to actively block interfering antibodies (HAAAs, RF, Heterophiles) by neutralizing them, allowing the binding of analyte/antigen to capture and detector antibodies to occur. Since active blocking reagents contain specific antibodies, they may typically be used in lower concentrations than passive blocking reagents.

|Goat anti-Human IgG Fc Fragment (Gamma Globulin Fraction)
|Catalog No. AB728-K
|Goat anti-Human IgG Fc Fragment. Affinity purified. (Gamma Globulin Fraction)

|Passive Blocking Reagents
|Passive blocking reagents comprise normal animal immunoglobulins and other components that essentially overwhelm and reduce the concentration of interfering antibodies by providing alternate binding sites to those of the detector and capture antibodies. Passive blocking reagents may be combined and/or used with active blockers to optimize formulations for specific assays.
