Prior to determining the activity of this enzyme, we reconstitute it in 20 mM sodium phosphate buffer, with 77 mM sodium chloride, 0.01% BSA, pH 7.0.
The dry weight of the product is not determined. The vial should contain a minimum of 300 units of enzyme.
The molecular weight for hyaluronidase from Streptomyces hyalurolyticus has been reported to be 91,000 DALTONS as determined by gel filtration.
No protein or BSA has been added as a stabilizer. The enzyme was lyophilized from 0.5 mM Tris buffer, pH 7.0.
Sigma assays the enzyme against a USP hyaluronidase reference standard as described in USP XXII-NF XVII, 644 (1990).
