Description

General description

Serine protease inhibitor. Active towards a wide range of serine proteases including granzymes. Not active toward β-lactamases.

Application

Useful in a rapid staining method for identification of macrophages; counts by this method were confirmed by the more complex morphological criteria, by phagocytosis, and by the presence of Fc receptors.

Preparation Note

Half-life = 20 min at pH 7.5.

Other Notes

Effective concentration 5-100 μM.
