Descrição geral

Hyaluronidase is widely present in nature.[1] In humans, it is present in a number of organs and body fluids. Hyaluronidase is found in the secretions of virus, bacteriophage, fungi and bacteria. It is also present in nematode and leeches secretions. Snakes and scorpions produce hyaluronidase in their venom. Hyaluronidase is also secreted by bees, spiders, wasps, hornets, caterpillars, fishes and lizards.[2]

Aplicação

Hyaluronidase from Streptomyces hyalurolyticus has been used:
  • in the preparation of DMEM/F-12 (Dulbecco′s modified eagle medium/nutrient mixture F-12) media for the isolation and purification of single cells from dissociated tumour tissue[2]
  • as a component of digestion solution for the derivation of germline stem cells from testicular tissue[3]

Ações bioquímicas/fisiológicas

Hyaluronate lyase cleaves hyaluronic acid at the β-D-GlcNAc-(1→4)-β-D-GlcA bond, yielding 3-(4-deoxy-β-D-gluc-4-enuronosyl)-N-acetyl-D-glucosamine tetra- and hexasaccharides. Unlike other hyaluronidases, this enzyme is specific for hyaluronic acid and is inactive with chondroitin and chondroitin sulfate.[4]
Hyaluronidase is an endoglycosidase and performs its function along with exoglycosidases, like β-glucuronidase and β-N-acetyl glucosaminidase. Hyaluronidase regulates the hyaluronic acid turnover.[1]

Definição da unidade

One unit will degrade 0.75 μg of the polysaccharide hyaluronic acid per minute at pH 5.35 at 37 ºC (as measured by turbidimetric absorbance (λ: 600nm) when complexed with BSA after 45 minutes).

Artigos

Explore the role of hyaluronan, hyaluronic acid structure, hyaluronan synthesis & degradation, and more. Find GAGs, hydrogels, and scaffold kits.

Uncover more about glycosaminoglycans and proteoglycans including the structure of glycosaminoglycans (GAGs), the different types of GAGs, and their functions.

Glycosaminoglycans are large linear polysaccharides constructed of repeating disaccharide units.

Protocolos

To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.

Questions

1–9 of 9 Questions  
  1. What is the volume in each vial/ampoule?

    1 answer
    1. H1136 is not supplied in solution form. The product is lyophilized directly into the ampule and its appearance is a clear, thin film.

      Helpful?

  2. You mention the following buffer composition for reconstitution: "...20 mM sodium phosphate buffer, with 77 mM sodium chloride, 0.01% BSA, pH 7.0". If I want to refreeze aliquots, would you suggest the same buffer? Isn't sodium phosphate harmful here?

    1 answer
    1. Long-term solution stability studies have not been performed on the microbial source hyaluronidase. However, the bovine source products are stable for up to 1 month at 4 deg. C (500 mM acetate buffer pH 6.0) and several months at - 20 deg. C. Aliquot solutions to store frozen, avoid repeated freeze/thaw cycles. The recommended reconstitution buffer should include 0.01% BSA which acts as a stabilizer, there is no indication that the recommended sodium phosphate/sodium chloride buffer would be inappropriate for freezing.

      Helpful?

  3. How is the activity of Product H1136, Hyaluronidase,determined?

    1 answer
    1. Sigma assays the enzyme against a USP hyaluronidase reference standard as described in USP XXII-NF XVII, 644 (1990).

      Helpful?

  4. I can't see any material in the container. Is material present in the container?

    1 answer
    1. The product is lyophilized directly into the ampule and its appearance is a clear, thin film.

      Helpful?

  5. What amount of product is present in the vial of Product H1136, Hyaluronidase?

    1 answer
    1. The dry weight of the product is not determined. The vial should contain a minimum of 300 units of enzyme.

      Helpful?

  6. What is the Department of Transportation shipping information for this product?

    1. No protein or BSA has been added as a stabilizer. The enzyme was lyophilized from 0.5 mM Tris buffer, pH 7.0.

      Helpful?

  9. What is the molecular weight of Product H1136, Hyaluronidase?

    1 answer
    1. The molecular weight for hyaluronidase from Streptomyces hyalurolyticus has been reported to be 91,000 DALTONS as determined by gel filtration.
