Method of determining chymase activity with secretory leukocyte protease inhibitor

摘要

It is now discovered that human chymase cleaves human SLPI at a specific site and that this cleavage can be used as an indicator of chymase activity. The present invention provides methods of diagnosing a chymase-associated disease or evaluating the efficiency of a treatment of a chymase-associated disease in a human subject by measuring SLPI processing, as well as other related methods and compositions.
