Equals approximately 8. Inhibitors: Fe2+ and Fe3+ are inhibitory as are Mn2+ and Cu2+ (Warren et al. 1962). Specificity: Testicular hyaluronidase hydrolyzes the endo-N-acetylhexosaminic bonds of hyaluronic acid and chondroitin sulfuric acids A and C (but not B), primarily to tetrasaccharide residues (Ludowieg et al. 1961). Monosaccharides are not liberated (Rappaport et al. 1951). Stabilizers: Yang and Srivastav (1975) report that sodium chloride acts as a stabilizer. Stability: hyaluronidase is stable for 1 - 2 years and the purified preparation for 6 - 12 months when stored at -20°C.
