Goat Serum blocking reagent or NGS can be used as a blocking agent to treat plastic surfaces, membrane or tissue after they have been sensitized with primary antibody or antigen. It provides an alternative to bovine serum albumin (BSA) and non-fat dry milk. It is effective in reducing nonspecific binding of proteins to reaction surfaces, thereby maximizing signal-to-noise ratio. This blocking agent is recommended for use in immunoassays where the primary antibody was produced in goat, as a source of non-specific serum protein or on tissue for immunohistochemical applications.

Application Note

Goat Serum blocking reagent or NGS has been tested by SDS-PAGE and is ideal for blocking procedures such as Western Blotting, ELISA and immunochemistry to prevent nonspecific binding.


Goat Serum blocking reagent or NGS was prepared from normal serum by a multi-step process which includes delipidation and selective precipitation.  Assay by immunoelectrophoresis resulted in a multiple precipitin arcs against anti-Goat Serum. Normal Goat Serum was obtained from non-immunized healthy goats.
