Audited Supplier Source: Bovine Pancrease
EC: 3.1.21.1
DESCRIPTION
Bovine pancreatic deoxyribonuclease (DNase) is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with free hydroxyl group at the 3' position and phosphate group at the 5' position. The optimum pH is 7.8. DNase I is activated by bivalent metals, and inhibited by chelating agents such EDTA and sodium dodecyl sulfate. DNase I can be stabilized against proteolytic digestion by 5 mM Ca2+.
Deoxyribonuclease has been chromatographically purified to remove trace contaminating proteases. DNase may be used in clinic to thin and liquefy mucus in the lungs.

Hyaluronidase, HAase
Source: mammalian testes
EC: 3.2.1.35
DESCRIPTION
Hyaluronidase is a glycoprotein containing 5% mannose and 2.7% glucosamine. Optimum pH range is 4.5-6.0. The enzyme catalyzes the hydrolysis of endo-N-acetylhexosaminic bonds of hyaluronic acid and chondroitin sulfate A and C (but not B), primarily to tetrasaccharide residues.
Hyaluronidase is extracted from bovine testes, and has been chromatographically purified to remove trace contaminating proteases.
