Goat anti Rat alpha-2 macroglobulin

The reactivity of the antiserum is restricted to rat alpha-2 macroglobulin. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal rat plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified alpha-2 macroglobulin. No reaction is obtained with any other plasma protein components or serum. In precipitating techniques as immunoelectrophoresis and single or double radial immunodiffusion (Mancini, Ouchterlony) to identify the presence of alpha-2 macroglobulin in rat plasma or other body fluids or to determine its concentration. This antiserum is not intended for use in non-precipitating antibody binding or other highly sensitive assays, but this does exclude such use if proper controls are included.
