Dornase alfa

Dornase alfa, sold under the brand name Pulmozyme, is used for the treatment of cystic fibrosis. It is a recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. Dornase alfa hydrolyzes the DNA present in sputum/mucus and reduces viscosity in the lungs, promoting improved clearance of secretions. It is produced in Chinese hamster ovary cells.
