特異性：Specific for alpha1AT as demonstrated by immunoelectrophoresis. A single precipitin arc is observed with normal plasma of identical mobility to that obtained with purified alpha1AT.
純度：Purified Purified by caprylic acid and ammonium sulfate precipitations, and solid -phase adsorption to remove unwanted crossreactivity.
形状：Supplied in 10mM HEPES, pH7.4, 0.1M sodium chloride and 50% glycerol.
