      Revision26-Febuary-2009 RFH
      DescriptionNative hyaluronidase from ovine testes. Catalyzes the hydrolysis of 1,4 linkages between N-acetylhexosamine and D-glucuronate residues in chondroitin, chondroitin-4-sulfate, chrondroitin-6-sulfate esters, and hyaluronic acid. Has an optimal pH of 4.5-6.0. Hydrolyzes the endo-N-acetyl-hexosaminic bonds of hyaluronic acid and chondroitin sulfate A and C to yield tetrasaccharide residues. Hyaluronidase activity is inhibited by the presence of Fe2+, Fe3+, Cu2+, and Mn2+.
      FormWhite lyophilized solid
      Recommended reaction conditions
      Assay Protocol Principle of Assay: Hyaluronic acid is measured by its ability to yield turbidity with an acidic albumin solution. The turbidity produced is a function of hyaluronic acid concentration and hence can be related to the activity of the enzyme. Reagents: 1N NaOH 0.3 M Sodium Phosphate Buffer, pH 5.3-5.35 Hyaluronic Acid Solution (0.2 mg/ml in 0.3 M sodium phosphate buffer, pH 5.3-5.35). May heat in a boiling water bath for a few minutes to dissolve. Alternatively, place at 4°C overnight. Stir for about 1 h on the next day to dissolve completely. Enzyme Diluent (0.02 M sodium phosphate buffer, pH 6.9, containing 0.45% NaCl and 0.01% BSA) 5N Hydrochloric Acid Acid Albumin Solution (10 mg of BSA, Fraction V, in 10 ml of 0.5 M sodium acetate buffer, pH 4.2). Adjust pH to 3.75 with few drops of 50 mM HCl. This solution is stable for 2 days at 4°C. Standard Hyaluronidase Solution (10 I.U./ml). Enzyme solution: Dissolve 10 mg of Hyaluronidase in 2 ml of ice-cold enzyme diluent (see above). Dilute to 2.0 I.U./ml just prior to use. Test Procedure: (Incubation temperature: 38°C; Wavelength; 600 nm; d = 1 cm) Preparation of Standard curve: Into a series of test tubes add reagents, as follows:

      Table 1: Preparation of Standard Curve

      1. Thoroughly mix and place the tubes at 38°C for 5 min. 2. At time zero add 1 ml of hyaluronic acid solution to each tube (for convenience allow 30 s intervals between each tube). Mix, stopper and incubate at 38°C for exactly 45 min. 3. Then add 10 ml of acid albumin solution to each tube and mix rapidly by inversion. Allow to stand for 5 min at room temperature. Read absorbance at 600 nm against a blank. 4. Construct a standard curve by plotting absorbance against the I.U./ml. Measurement of Hyaluronidase Activity: Pipette 1 ml of each diluted sample into test tubes at 38°C and repeat steps 1 to 4 (see above). Obtain hyaluronidase concentration (I.U./ml) for each sample solution using the standard curve.
