Proteinase 3/Myeloblastin/PRTN3: ELISA Kits

Myeloblastin (PR3) is a polymorphonuclear leukocyte serine protease which degrades elastin, fibronectin, laminin, vitronectin, and collagen types I, III, and IV (in vitro) and causes emphysema when administered by tracheal insufflation to hamsters. PR3 plays a role in neutrophil response to inflammation.
