索取COA

  1. 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.

  2. 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.

  3. 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. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

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

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Do you have any information on the traceability to a recognized protein standard, such as NIST? Or is the concentration derived from accepted values of natural physical constants?

    The concentration of each lot of the protein standard, Product P0914, is determined by UV measurements. Specifically, given a known extinction coefficient (E) and a measured absorbance (A), and assuming a standard pathlength of 1 cm, the concentration (c) can be determined by Beer's Law (c = A/E). The assay result is derived from an accepted value of a natural physical constant. Specifically, the E1% of 6.67 at approximately 279 nm is a well-accepted value, originally published in J. Am. Chem. Soc., 78, 3656-3660 (1956).
