      Revision07-July-2009 JSW
      DescriptionNative hyaluronidase from Streptomyces hyaluronlyticus nov. species. Catalyzes the degradation of hyaluronic acid. Produces δ4,5-unsaturated tetra- and hexasaccharides.

      Please Note: The appearance of this product can vary from gray cottony fibers to balled up droplets with no change in quality.
      FormWhite lyophilized powder
      Recommended reaction conditionsAssay for Enzymatic Activity Reagent Preparation Prepare acetate buffer: 150 mM NaCl, 20 mM sodium acetate-acetic acid buffer, pH 6.0. Prepare hyaluronic acid solution: 50 mg purified potassium hyaluronate (containing approximately 38% glucuronic acid) is dissolved in 100 ml of the above mentioned sodium acetate buffer. Measure acidic bovine serum albumin with a spectrophotometer at 280 nm. Adjust the total absorbance of the albumin solution to 910. Dilute to 100 ml with 0.5 N acetate buffer, pH 4.3. Adjust the pH of the albumin solution to 3.1 using 4 N HCl. Boil in a water bath for 30 min at 100°C. Adjust to 100 ml with distilled H2O. This solution is stable for 3-4 weeks at 4°C. To use this solution, dilute with 5 volumes of acetate buffer from above. Activity Protocol For the assay, mix 0.5 ml of the enzyme solution (made with acetate buffer without NaCl) with 0.5 ml of the hyaluronic acid solution. Incubate for 30 min at 60°C. Add 4 ml of the acidic bovine serum albumin solution. Incubate for 10 min at 60°C. Measure the turbidity at 660 nm. Obtain a blank value by using deactivated enzyme (incubate at 100°C for 10 min). Correct the reading by subtracting the blank value. (blank value - measured value/blank value) x 2 x 2 x dilution = TRU/ml
