法规信息
How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
How is Hyaluronidase from bovine testes, Product H3506, solubilized?
It is soluble at 1 mg/ml in 0.02 M phosphate buffer, pH 7 containing 77 mM sodium chloride and 0.01% bovine serum albumin.
How is a solution of Hyaluronidase from bovine testes, Product H3506, stored?
Prepare fresh solutions directly before use since stock solutions are not stable for storage.
Can Hyaluronidase from bovine testes, Product H3506, be used on humans?
No. None of our packaged research products are for human use.
What is the shelf life of Product H3506, Hyaluronidase from bovine testes?
Product H3506, Hyaluronidase from bovine testes, has a Recommended Retest period of two years (period of time between the Quality Control Release and Recommended Retest dates). This date assigns the time frame during which the batch is expected to remain within established specifications if stored under Sigma-Aldrich’s defined conditions, which for product H3506 is at -20°C. This information is provided on the Product's lot specific Certificate of Analysis.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I find price and availability?
There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

实验方案
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.
在测定透明质酸酶活性时，使用了一种在600 nm处的比浊测定法进行测定。在pH 5.35、37 °C下，一单位的透明质酸酶活性可每分钟引起0.330的吸光值改变。
