Based on immunoelectrophoresis and/or ELISA, the antibody reacts with peroxidase from horseradish roots.It may cross-react with peroxidase from other sources.
18 nm Colloidal Gold
Colloidal gold reagents for transmission and scanning electron microscopy (EM Grade) are distinguished from other commercial preparations by careful separation of monomeric particles from small aggregates using ultracentrifugation in density gradients. The resulting monomeric colloidal gold-protein complexes are suspended in sterile-filtered buffer containing stabilizers and a preservative. All particle sizes in the EM Grade category may also be used for light microscopy and immunoblotting by those who prefer to use particles larger than 4 nm.
