  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. How stable are solutions of Product L2157, Laccase from Rhus vernicifera?

    Solutions should be prepared fresh, directly before use, as they are not stable as stock solutions.

  6. My solution of Product L2157, Laccase from Rhus vernicifera, isn't clear. Is this normal?

    Yes. L2157 is a crude acetone powder, and can contain other proteins, enzymes, and cellular debris.  A suspension may be prepared in 100 mM potassium phosphate buffer, pH 6.5, by homogenization with a hand-held homogenizer for 10 minutes. This preparation may then be centrifuged; the laccase activity will be present in the supernatant.

  7. What is the molecular weight (MW) of Product L2157, Laccase from Rhus vernicifera?

    Spira-Solomon and Solomon, J. Am. Chem. Soc., 109, 6421-6432 (1987) reports estimated molecular weights of 52 kDa (laccase 1), 55 kDa (laccase 2), and 70 kDa (laccase 3), as determined by gel filtration.

  8. What is the pH optimum of Product L2157, Laccase from Rhus vernicifera?

    Our own assay is performed at pH 6.5.  One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives pH 6.5 as another value for the laccase from this species, with a range for enzyme activity of 4.3 to 9.

  9. What is the temperature optimum of Product L2157, Laccase from Rhus vernicifera?

    Our own assay is performed at 30°C.  One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives 25°C as another value for the same enzyme from the same species.

Numerous efforts have been made to remove emerging trace organic contaminants, such as pharmaceuticals and personal care products (PPCPs). This study examined the removal of N,N-diethyl-m-toluamide (DEET) by Trametes versicolor laccase and its laccase-mediator systems. Experimental results showed that DEET

We report the functionalization of multi-walled carbon nanotube (MWCNT) electrodes by oxidative electropolymerization of pyrrole monomers bearing pyrene and N-hydroxysuccinimide groups. Both polymers were applied to the immobilization and electrical wiring of Trametes versicolor laccase via chemical grafting or non-covalent
